1.0 SUMMARY

1.1 The proposal amends the recently approved scheme that retained the building façade to Chiswick High Road and Upham Park Road. The retention of the façade is not structurally feasible and this proposal to redevelop the site includes the demolition and reconstruction of the existing front and side facades of the building facing Chiswick High Road and Upham Park Road. The rear elevation is a newbuild façade in a mixture of used stock bricks and render. The existing roof is a single pitch. The proposal includes a two-slope mansard roof.

1.2 As per the approved scheme, the current application proposes a retail or

business unit at ground floor and basement for A1, A2 or (new to the current scheme) B1 use (445m2), as approved seven flats (2 x 1 bed and 4 x 2 bed apartments and 1 x 3 bed penthouse apartment and 2 x 3 bed detached houses are proposed. The scheme also includes provision for 10 car parking spaces at basement level accessed via a car lift, 9 cycle spaces also at basement level but accessed via the main pedestrian lift and refuse and recycling storage areas at ground floor level.

2.0 SITE DESCRIPTION

2.1 The application site has an area of 0.07 hectares and is located on a corner site with Chiswick High Road to the south and Upham Park Road to the east. The site is in a prominent location at the junction of two major arterial roads – Chiswick High Road (A315) which runs in an east-west direction through Chiswick Town Centre and Chiswick Lane South (A316) which provides an important north-south link between the M4/A4 to the A40.

2.2 The site lies at the eastern end of Chiswick Town Centre and is within the

designated town centre boundary as shown on the Unitary Development Plan Proposals Map. It is not, however, within the designated shopping frontage although the existing retail frontage of the town centre does extend to the site.

2.3 The existing premises comprise three 3-storey Victorian properties with

additional habitable floors within the roofs. The upper floors of the buildings retain the appearance of three terraced houses with bay windows on the first floor. At roof level each property has a pitched roof which includes two front door windows with velux windows on the rear roof slopes.

- 3 -

2.4 The existing property is a maximum of 3.8m higher than the adjoining 3-storey terraced Edwardian properties to the west of the site at the top of the pitched roof. The upper floors of the premises are set back from the adjoining Edwardian terrace but the interlinked ground floor, used as a car showroom and sales area, has been extended forward in line with the adjoining terrace. The aluminium shopfront with extensive area of glazing and prominent fascia signage advertising LMC extends across all three properties and continues round the corner into Upham Park Road. No. 104 has been extended at the rear with a single storey pitched roof building and is now used as a service centre.

2.5 A separate detached garage is located at the back of the building adjacent

to No. 1A Upham Park Road. This is also used for servicing and storage of cars.

2.6 The premises are used as a car showroom and sales area on the ground

floor and yard to the rear. 2.7 The first floor of Nos. 104 and 106 is used for offices with residential on the

two floors above. All of the accommodation on the three upper floors of No. 108 is used for residential purposes.

2.8 The site is located on the edge of Chiswick Town Centre which offers a

good range of shops, restaurants, offices and other services. Turnham Green Underground Station is 400m to the west of the site and Stamford Brook is 700m to the east of the site. Both stations provide access to the District line with routes to Central London, Ealing, Richmond, Heathrow and other destinations.

2.9 The premises are not included on the statutory list of buildings of

architectural or historic importance. They are not locally listed and are not within a conservation area.

3.0 HISTORY 3.1 The car showroom/sales use has been in operation for at least 30 years.

Since the purchase of the premises by LMC Ltd some 18 years ago the only changes to the premises have involved installation of the aluminium shopfront, the signage and the shed at the rear.

3.2 00248/104

-108/P1 Demolition of the existing building, and erection of two new buildings – one new mixed use building comprising 895m2 retail (A1) floorspace and 9 new residential units and one new building comprising up to 132m2 (B1) office floorspace thereto.

Refused: 14/08/2008

Summary of reasons: 1. The proposed development, by reason of its height, massing and external appearance, would unduly harm the appearance and form of the streetscene and would appear overly

- 4 -

dominant in the street scene to the detriment of the local townscape.

2. The proposed development fails to provide adequate living space, due to the location of windows and private amenity space for the occupants of the new dwellings.

3. The proposed development, is considered to be an over intensification of the site, resulting in unsatisfactory residential accommodation for future occupiers due to the inadequate amenity space provision, accessibility and no provision for loading and unloading.

4. The proposed arrangements for deliveries and servicing of the commercial units are inadequate, and are likely to give rise to conditions prejudicial to the free flow of traffic on the public highway and increase in danger for traffic and pedestrians.

5. The proposed development does not create an inclusive residential and office development, in particular no provision has been made access for people with disabilities.

6. The proposed development, by reason of its height, massing and bulk, be unduly detrimental to the outlook of neighbouring residents.

7. The proposed development makes inadequate provision for improving energy efficiency and increasing the proportion of energy used generated from renewable sources.

The scheme was appealed and the appeal was dismissed by the Planning Inspector based on design issues and the lack of useable amenity space for future residents.

3.2 00248/104-108/P2

Part demolition of the existing building retaining the existing shopfronts, front elevation and elevation to Upham Park Road with new building behind facades to provide mixed use development comprising 504 sq m commercial floor area (A1 or A2 uses only) to ground floor and basement, with 7 flats to three upper floors, erection of two dwellinghouses to rear, and associated amenity space, basement car parking, bicycle storage, and recycling and refuse storage

4.0 DETAILS

4.1 The proposal amends the recently approved scheme that retained the building façade to Chiswick High Road and Upham Park Road. The proposal includes the demolition and reconstruction of the existing front and side facades of the building facing Chiswick High Road and Upham Park Road. The rear elevation is a new build façade in a mixture of used stock bricks and render.

4.2 Initial opening up works have been undertaken by the applicant to expose

the existing support system of the street elevation masonary façade. Having undertaken a designers risk assessment for the proposed retention strategy, the developer considers that ‘the severity of a collapse may be unacceptable compared to the risk of an incident occurring’. As such, the current scheme proposes the demolition of the whole building with the shopfronts and the front and side façade to be rebuilt to replicate the existing.

4.3 The rear elevation is a new build façade in a mixture of used stock bricks and render. The existing roof is a single pitch. The proposal increases the width of the roof, which includes two-slope mansard roof. The scheme comprises a retail or business unit at ground floor and basement for A1, A2 or B1 use (445m2).

4.4 The key differences between the approved scheme (P2) and the proposed scheme are summarised below:

• The proposal includes the demolition and reconstruction of the existing front and side facades of the building facing Chiswick High Road and Upham Park Road;

• Introduction of Anthra Zinc Clad vent flues set 7m back from the Chiswick High Road frontage that would project 1m above the approved roof slope, the vent flues. Their function is to act as vents for the ventilation of the flats.

• Zinc dormer to rear elevation of existing building to increase in height by 0.52m and length increased by approximately 3.97m with a new window with obscure glass;

• Height of car lift enclosure increased by approximately 1.04m; and

• The proposed 445m2 A1 and A2 retail unit at ground floor and basement is also proposed to be able to accommodate B1 business uses.

4.5 Seven apartments would be provided on the upper floors with a gross floor area of 732m2. The first and second floors would contain 1x1 bedroom and 2x2 bedroom apartments each.

- 6 -

4.6 The third floor would contain a 3-bedroom apartment.

4.7 Two, 3 bedroom houses with a total gross floor area of 288m2 are proposed at the rear of the site.

4.8 In summary approximately 33% of all units proposed in the scheme would be large family sized units, with 3 or more bedrooms. A further 3 of the units would have two bedrooms. Therefore, in total 66% of the units would be family sized.

4.9 The commercial/business unit would be accessed off Chiswick High Road. The apartments and individual houses would be accessed off Upham Park Road. Disabled compliant lifts would serve the upper floors. Other than these changes, the proposed development is the same as that previously approved.

4.10 Each of the proposed flats has access to a shared, soft landscape garden in the north-west corner of the site at ground floor level. The individual houses have rear gardens and roof terraces.

4.11 The proposed development generates a density of approximately 382 habitable rooms per hectare based on a net site area of 732m2.

4.12 An Air Source Heat Pump (ASHP) system and Solar Hot Water (SHW) panels to supply domestic water to residential units are the most feasible options for on-site renewable energy production and have been incorporated into the proposal.

4.13 The proposed scheme includes a basement car park with space for 10 cars and 9 secure cycle spaces in the basement. The car park would be accessed via a car lift from Upham Park Road whilst bicycles could be transported via the main pedestrian lift which serves all floors including the basement.

4.14 A Structural Consideration report was submitted as part of the application. The report notes that having undertaken a designers risk assessment for the proposed façade retention strategy approved as part of the previous

- 7 -

planning application and that the retention of the façade would involve inherent risks and is not considered feasible structurally.

4.15 The scheme would be constructed of a yellowish Kentish Reserve brick from Hanson, cedar timber panels and doors would be incorporated as would self-finished white render above the doors of the car lift. The proposal would incorporate composite aluminum windows. An elevational plan is shown below.

4.16 The recessed roof terraces for the new houses would have an external zinc cladding as would the rear roof projection of the main building.

5.0 CONSULTATIONS

5.1 As part of the Council’s consultation, letters were sent to 153 owners/occupiers of Chiswick High Road, Upham Park Road, Thornton Avenue & Cranbrook Road. A site notice advertising the application as a major application was posted on 30/11/2010, and the application was advertised in the local press on 03/12/2010. At the time of writing 3 responses had been received including one from the Thornton-Mayfield Residents Association letter objecting to the proposal. Another response has also been received neutral to the proposed development. A summary of the relevant issues of objection from the submissions and a response is given below, with the exception of the comment relating to the demolition of the existing building the comments remain the same as that previously raised.

Comment Response

- 8 -

The proposal introduces many very large new windows and also terraces and roof top patios overlooking gardens in Chiswick High Road, Upham Park Road and Thornton Avenue which will seriously devalue the amenity of these spaces and houses.

The location of roof terraces and balconies relative to the nearest habitable room windows has not altered in a way that would increase overlooking opportunities from the previously approved scheme. Refer to paragraphs 7.42 to 7.45.

The building is already hugely overpowering in the street scene and further increases in both its height and depth are not justifiable

Refer to paragraphs 7.7 to 7.17. However, the scale of the buildings are considered acceptable and are not significantly greater than that previously approved.

The elevations proposed for the proposed new builds to the Upham Park Road are completely unacceptable in a Victorian/Edwardian area.

Refer to paragraphs 7.7 to 7.17. However, the design of the new build houses facing Upham Park road has not altered significantly from that previously approved.

Oppose the concept of demolishing an existing Victorian façade to the main building and constructing in its place an imitation Victorian building and the demolition of the existing Victorian chimneys and Flemish style stepped party wall upstands and the substitution for zinc lumps mimicking the originals

The subject building is not located in a Conservation Area and is not Listed. As such, it could be demolished without requiring planning permission. The applicant has submitted information showing that the retention of the facades (as approved) is not feasible.

The proposed development should be conditioned so that no resident or occupant of the proposed development will be entitled to either resident or business car parking permits.

It is recommended that any approval be subject to a legal deed stating that occupiers of the flats should not be eligible for parking permits within the CPZ.

The security of our property is paramount during this process and we expect the developers to ensure that there is no degradation of that from our current situation.

Noted

That there is strict adherence to Council guidelines on working hours and noise pollution. We do not expect deliveries of materials or other forms of noise to disturb outside those set hours

Agreed, it is recommended that any approval be subject to conditions restricting the hours of construction.

Given the scope of the works we expect there to be no degradation

Agreed, it is recommended that any approval be subject to conditions

- 9 -

expect there to be no degradation to the upkeep and cleanliness of the road, drains and pavements, in particular as a result of site traffic and mud from the excavation.

approval be subject to conditions requiring a construction management plan be in place to ensure that would address these points.

Mechanical noise from the lift for the subterranean car park should not be heard from neighbouring properties

The Council’s Acoustic experts have reviewed the submitted noise report and have received additional confirmation of the safeguarding measures implemented. It is considered that the proposed car lift would provide a good degree of practical isolation of both the motor and the lift shaft.

5.2 Letters of consultation were also sent to the following statutory bodies:

• Environment Agency;

• Metropolitan Police – Crime Prevention Office;

• Primary Heath Care Trust.

7.0 PLANNING ISSUES

7.1 The main planning issues to consider are:

• The principle of the development

• The siting, massing and design of the proposed building

• Is the proposal acceptable in housing terms?

• Housing standards, quality and the effect on neighbours

• The implications for traffic and Parking in the Locality • Sustainability Issues

Issue 1: THE PRINCIPLE OF THE DEVELOPMENT

7.2 The principle of the redevelopment of the site to provide a mixed use scheme on the site was established with the recent planning permission 00248/104-108/P2. The key differences between the approved scheme (P2) and the proposed scheme are summarised below:

- 14 -

• The proposal includes the demolition and reconstruction of the existing front and side facades of the building facing Chiswick High Road and Upham Park Road;

• Introduction of Anthra Zinc Clad vent flues set 7m back from the Chiswick High Road frontage that would project 1m above the approved roof slope, the vent flues. Their function is to act as vents for the ventilation of the flats.

• Zinc dormer to rear elevation of existing building to increase in height by 0.52m and length increased by approximately 3.97m with a new window with obscure glass to creat larger living accommodation for one of the units;

• Height of car lift enclosure increased by approximately 1.04m; and

• The proposed 445m2 A1 and A2 retail unit at ground floor and basement for is also proposed to be able to accommodate B1 business uses.

7.3 However, the mix, no of dwellings and the floor area are as per the previous approved application. Therefore it is consistent with the housing and employment policies detailed below and the principle of the development is acceptable.

7.4 Planning Policy Statement 3 (PPS 3), the London Plan and the Unitary

Development Plan 2003 (UDP) seek to maximise housing on previously developed sites. Policy 3A.3 of the London Plan states that boroughs should ensure that development proposals achieve the highest possible intensity of use compatible with local context, and encourages well designed buildings with good access to local shops, services, employment and public transport.

7.5 Furthermore, the retention of commercial retail use of the ground and basement floors is encouraged and is in line with Policy IMP.2.4 (Enhancement of Chiswick Town Centre). The site is located within the designated Chiswick Town Centre, and it is on Chiswick High Road where commercial retail uses are appropriate and the site will provide continued retail business and employment opportunities that will benefit the local economy.

7.6 The previously approved scheme for the redevelopment of this site allowed for the retention of the existing shopfronts and front and side façade with a new building to the rear. However, initial opening up works have been undertaken by the applicant to expose the existing support system of the street elevation masonary façade. Having undertaken a designers risk assessment for the proposed retention strategy, the developer considers that ‘the severity of a collapse to be unacceptable compared to the risk of an incident occurring’. As such, the current scheme proposes the demolition of the whole building with the shopfronts and the front and side façade to be reconstructed to match the existing. Council Officers have met with the applicant’s surveyor and have assessed the submitted Structural Consideration report and accept the conclusions reached. Given the evidence submitted, it is considered that the principle of the demolition of

- 15 -

the existing building and rebuilding the front and side façades is acceptable, subject to the facades being reconstructed to match the details and quality of the existing building.

Issue 2: THE SITING, MASSING AND DESIGN OF THE PROPOSED BUILDING

7.7 PPS3, at Paragraph 12, states that good design is fundamental to the development of high quality new housing, which contributes to the creation of sustainable, mixed communities. Following this, and reflecting policy in PPS1, Paragraph 13 of PPS3 states that design which is inappropriate in its context, or which fails to take the opportunities available for improving the character and quality of an area and the way it functions, should not be accepted.

7.8 UDP Policy ENV-B.1.1 (New Development) requires new development to make a positive contribution to overall environmental quality. In relation to the context, form and layout of the buildings and spaces, new development should relate well to its site and the scale, nature, height, massing and character of the adjacent townscape and respect the proportions of neighbouring buildings where there are strong uniform design characteristics.

7.9 The existing buildings on Chiswick High Road adjacent to the site display a

strong vertical emphasis and rhythm, formed by the regular spacing of the windows and pilasters. The proposed scheme like that previous approved (00248/104-108/P2) has been designed to take into account the matters raised by the Local Planning Authority during pre-application discussions and the Appeal decision with regard to height, massing and scale of development.

7.10 The proposed scheme would increase the massing of the existing building to its rear, however the scale of the proposed development is significantly less than that of the previously refused scheme. When compared to the previously approved scheme, the key changes with regards to scale are that the height of the car lift enclosure adjacent to 1A Upham Park Road has increased by approximately 1.04m; and the zinc dormer on the rear elevation of main building would increase in height by 0.52m and the length of the dormer would increased by approximately 3.97m with a new window with obscure glass.

7.11 The proposal involves a reconstruction of the roof to create greater volume with a dual pitched mansard roof to replace the existing single pitched roof. It is considered that the proposed roof when viewed from the surrounding streetscape would not appear at odds with the character of the surrounding streetscape. The newly proposed vent flues are designed to provide emphasis to the vertical division of the building elevation. It is divided into three sections on the party wall lines.

7.12 The existing 2-storey element at the rear would be extended up to 3-

storeys. The proposed development then steps down to the same height as

- 16 -

the existing dwellings along Upham Park Road. It is considered that the reduction in height would not destroy the calm regularity that exists on this section of the road at present.

7.13 The proposed new dwellings are of a contemporary design creating a

distinct transition between the Victorian façade of the main building and the Victorian terraced properties on Upham Park road. The only change to the houses from that previously approved is that the proposed balcony and conservatory/study of the house nearest to the adjacent property at 1a Upham Park Road, would be re-positioned to the edge of the roof terrace approximately 4.3m from 1a Upham Park Road. It is considered that the design of these dwellings would respect the character of the adjoining residential properties in terms of height and scale. As noted earlier, the parapet line of the dwellings would line up with the eaves line of the adjoining property No. 1A Upham Park Road.

7.14 The existing shopfronts along Chiswick High Road are to be rebuilt to

replicate the existing but would include the replacement of lost pilasters and cornice features. The proposed shopfronts and fascias would be set between the pilasters and the appearance of the frontage would provide an improvement to the existing appearance of the property which has large fascia boards extending across the pilasters. The shopfront would also turn the corner into Upham Park Road to create more ground floor interest at this prominent corner location.

7.15 With regards to the impact of the proposal on the outlook from the adjoining properties, it is noted that the proposal would not bring development closer to 1A Upham Park Road than the previously approve scheme, which is the residential site most likely to be impacted by the development. However, as noted by the Planning Inspectorate when considering an earlier appeal scheme (P1):

the principal effects would relate to the side of the house, whereas much of the property’s outlook is derived from windows to the front and rear. Furthermore, the outlook to the side, including that from the roof terrace, is currently compromised by the use of part of the appeal site as a yard storing and preparing cars. Any effect on the garden would be limited due to the high wall that separates it from the appeal site. Overall, therefore, I do not consider that the proposal would cause unacceptable harm to the outlook of No 1A.

7.16 Given that no habitable room windows are located on this adjacent façade, it is considered that the repositioning of the conservatory/study would not adversely impact on the living conditions of this neighbour. It is also considered that the conclusions reached by the Planning Inspectorate remain applicable to the current application and the proposal would not cause unacceptable harm to the outlook from adjoining residential properties.

7.17 Overall, a scheme with potential to meet the Council’s planning objectives is proposed and the standard of provision appears to have the capacity to meet the Council’s layout and design standards and would sit comfortably

- 17 -

within the street scene without impacting on the calm regularity that currently exists.

Issue 3: IS THE PROPOSAL ACCEPTABLE IN HOUSING TERMS?

7.18 PPS3 sets out the national planning policy framework for delivering the Government’s housing objectives. The Government’s key housing policy goal is to ensure that everyone has the opportunity of living in a decent home, which they can afford, in a community where they want to live (Paragraph 9).

Density

7.19 Residential density is a tool against which an initial appraisal is made. It is a useful guide to the nature of the development and can be used to ensure that new development reflects the character of an area, but is not a determinant in its own right.

7.20 Table 3A.2 of the London Plan illustrates appropriate densities to be achieved in relation to housing. The site has a PTAL of 5, which is defined as “very good”. Table 3A.2 of the London Plan sets the relevant density range for a development comprising of flats in this location as 200-700 hr/ha. The proposed development generates a density of approximately 382 hr/ha based on a net site area of 732m2, which is within the range stipulated in the London Plan, though as noted, the development must be compatible with the local context and design principles from policy 4B.1. The density is unchanged from the recently approved scheme (P2).

7.21 While the proposed density is within the range established by the London Plan, the merits of the scheme and the quality of the accommodation provided needs first to be taken into consideration. These issues are assessed in the following paragraphs.

Issues 4: HOUSING STANDARDS, QUALITY AND THE EFFECT ON NEIGHBOURS

7.22 The residential component of the scheme consists of the following housing types, which are unchanged from the recently approved scheme (P2):

� 2 x 3 bedroom houses (Units 1 & 2) [144m2];

� 2 x 2-bedroom apartments (Units 3 & 6) [72m2 and 68m2];

� 2 x 2-bedroom apartments (Units 5 & 8) [82m2];

� 2 x 1-bedroom apartments (Units 4 & 7 [52m2 and 48m2];

� 1 x 3-bedroom apartment (Unit 9) [223 m2]

7.23 In summary approximately 33% of all units proposed in the scheme would be large family sized units, with 3 or more bedrooms. A further 3 of the units

- 18 -

would have two bedrooms. Therefore, in total 66% of the units would be family sized.

Accessibility

7.24 The London Plan strongly supports the principle of Lifetime Homes and views them as a fundamental key to the delivery of the Government’s objectives of social inclusion, sustainability, equality and valuing diversity and identifies that the increased independent living they can bring will reduce pressure on hospital beds and residential care homes. Policy 3A.4 (Housing choice) proposes that all new dwellings should be built to Lifetime Home standards.

7.25 The Mayor’s Supplementary Planning Guidance Accessible London: Achieving an Inclusive Environment (April 2004) sets out that the target of 10% of new dwellings shall be wheelchair accessible should be applied to both market and affordable housing and makes clear that the requirements of a wheelchair accessible dwelling are in addition to Lifetime Home standards.

7.26 Also relevant is London Plan Policy 4B.5 (Creating an inclusive environment), which requires all future development to meet the highest standards of accessibility and inclusion.

7.27 The applicant has advised that all homes have been designed to lifetime home standards, and the commercial unit would be fully compliant with Part M Building Regulation requirements for access for people with disabilities.

7.28 A disabled compliant lift would serve the upper floors of the flats and the houses could be converted to be wheelchair accessible.

Amenity space

7.29 The provision of good quality private useable amenity space and children’s play areas is key in all levels of the planning framework.

7.30 Private amenity space standards are set out in the UDP SPG. The 7 units proposed would, based on 24 habitable rooms, generate a private amenity space requirement of 190m2. This is calculated on the basis of the number of habitable rooms in a dwelling. Each of the one and two bedroom units is considered to have 3 habitable rooms or less, meaning each requires 25m2. The three bedroom flat has 5 habitable rooms and therefore requires 40m2. These figures are calculated using the figures stipulated in Paragraph 4 of Section 10: Private Amenity Space of the SPG. In addition the proposed two-bedroom house would require a private amenity space with a minimum area of 50m2.

7.31 The scheme remains unchanged from that previously approved (P2) and includes a 155m2 communal amenity space at the rear of the site for use by the residents of the apartments. This space can be directly accessed from the rear of the apartment building. The space is the same as that previously considered acceptable by the Council.

- 19 -

7.32 The proposed 3-bed apartment would include a 10m2 private balcony. In light of the recent Planning Inspectorate decision, it is considered that balconies on the rear elevation would be acceptable from an overlooking perspective.

7.33 The proposed houses would have roof terraces and, private rear gardens

and small front gardens. The total area of amenity space available to future residents of the proposed houses is approximately 52m2.

7.34 The site is only about a 5-minute walk from Homefield Recreation Ground,

which could make an important contribution to the playspace needs of children in the locality. The site does not fall within an area of open space deficiency, and the Local Planning Authority did not seek any contribution in relation to public open space during the previous appeal process owing to the town centre location of the site.

7.35 In summary, the scale of amenity space provided on site is lower than the

level of amenity space sought within the planning framework. However, given the town centre location of the site, the size and general north/south orientation of the proposed communal amenity space combined with the balcony of the larger family apartment and the private gardens and terraces associated with each of the individual houses, it is considered that, on balance, sufficient amenity space would be provided on site to meet the anticipated needs of future residents.

Internal space standards

7.36 Section 12 of the Council’s 1997, Supplementary Guidance sets minimum standards to be achieved for internal floor areas in new dwellings. These floor area standards are set out in the table below.

Floor area standard (sq.m) Number of occupants UDP Supplementary Planning Guidance (February 1997)

1 30

2 45

3 57

4 70 for a flat, 72 for a two-storey house or a maisonette

5 79 for a flat, 82 for a two-storey house or a maisonette, 94 for a three-storey house

6 86 for a flat, 92 for a two-storey house or a maisonette, 98 for a three-storey house

7.37 Each of the proposed units complies with these requirements. The Supplementary Guidance also lists appropriate minimum room sizes. However, these are to be applied to conversions and a more flexible approach to internal spaces standards can be adopted in new developments. It is considered that the size and layout of the proposed units

- 20 -

accords with the intent of the Council’s and London Plan policies and Guidance.

Daylight and Sunlight

7.38 UDP Policy ENV-B.1.1 (New Development) states that in relation to the context, form and layout of buildings and spaces, new development should “ensure adequate daylight and sunlight reaches properties, and minimise any detrimental impact on adjoining properties, by applying the Council’s adopted standards (see SPG).” The reference to adopted standards (see SPG) is to the UDP Supplementary Planning Guidance (February 1997), which gives daylight and sunlight standards at Section 4.

7.39 The applicant has previously submitted a Sunlight and Daylight study.

7.40 The Building Research Establishment’s guideline: ‘Site layout planning for daylight and sunlight – A guide to good practice’ states that with regards to gardens and open spaces that no more than two fifths, and preferably no more than a quarter of gardens, children’s playgrounds and sitting out areas should be prevented by buildings from receiving any sunlight at all on 21st March. The technical analysis previously submitted illustrates that 46% of the shared courtyard would be overshadowed on March 21st. This equates to an extra 7.2m2 of overshadowed space when compared to a complying scheme. The applicant has also commissioned a study which shows that on March 25th, approximately 37% of the amenity space would be overshadowed.

7.41 An assessment of the impact of the changes to the proposed scheme from that previously approved on the level of sunlight and daylight received at adjoining properties has been undertaken and concludes that the proposal would not result in additional overshadowing when compared to the approved scheme. It is noted that at the earlier Planning Inquiry, the Inspector considered that the previous appeal scheme would not have an unduly harmful impact on the sunlight, daylight, outlook or privacy of the residents of adjoining properties. The building mass of the current scheme has been significantly reduced from that assessed at appeal and the proposal would not adversely impact on the level of sunlight and daylight received at any adjoining property.

Privacy

7.42 UDP Policy H.4.1 (Housing standards) requires proposals to, amongst other things, have regard to standards and guidelines for privacy and spacing between buildings. These are set out at Appendix 1 of the UDP and read,

� The design and layout should ensure sufficient privacy intended residents and to a smaller area of garden close to each dwelling…

� A distance of at least 21m (70ft) is recommended between the habitable room windows which directly face those of another habitable room, or any other windows that give light and outlook to rooms normally occupied during the day. In the case of windows of non-habitable rooms within 21m of another facing window, obscured glazing would be

- 21 -

considered acceptable.

� Roof terraces and balconies are not acceptable where they would directly overlook neighbouring habitable rooms or gardens.

� In calculating the effects of a particular development on outlook, the natural features of the site, including slope, will need to be taken into account, together with the effects of existing and potential extensions.

7.43 When assessing the privacy implications of the earlier appeal scheme, the Planning Inspector noted:

Ground floor windows in 1A are shielded by the wall that separates it from the appeal site and the side of the proposed office building would be free from openings. While there would be windows and balconies facing towards 1A in the larger of the buildings, obscure glazing and screens are proposed to restrict views from these. Consequently I do not consider that there would be harmful overlooking or perception of overlooking of No 1A.

7.44 The proposed scheme does not differ from that approved under planning reference 00248/104-108/P2 in that it would introduce roof terraces to the proposed houses. It is noted that the houses are orientated such that the predominant views would be across the rear yards of the commercial premises along Chiswick High Road, rather than out towards the roof terraces and rear gardens of the properties along Upham Park Road or Thornton Avenue. In addition, the separating distances between the roof terraces and neighbouring residents has not altered from that previously deemed to be acceptable.

7.45 The proposed roof terraces and penthouse balcony would incorporate 1.1m high London stock brick walls with an additional 0.4m high, 10mm thick toughened obscure glass privacy screen. It is considered that given the separating distances to adjoining habitable room windows, the proposed balcony and roof terrace details would be sufficient to ensure that the proposal does not unreasonably harm the privacy of neighbouring residents.

Noise Impact

7.46 An Environmental Noise Assessment has previously been carried out by Sharps Redmore Partnership on behalf of the developer. An assessment of road traffic noise according to PPG 24 has shown that the site falls within Noise Exposure Category (NEC) C. PPG 24 indicates that in these circumstances planning permission can be given for residential development provided that appropriate conditions are placed on any approval requiring protection against noise. The noise issues associated with the proposed development remain unchanged from that previously deemed acceptable (P2).

7.47 The Council’s Environmental Pollution Control Team have previously confirmed that adequate mitigation of noise issues can be achieved through design and suitable double glazed windows.

7.48 To ensure that the proposal accords with UDP Policies ENV-B.1.1 and ENV-P.1.5, if the Council were minded to approve the application, it is

- 22 -

recommended that it be subject to a condition requiring the residential units to incorporate a double glazed or a secondary/hybrid secondary glazed system and a minimum level of sound attenuation for ventilation on key facades i.e. acoustic trickle ventilators or acoustic wall ventilators.

7.49 With regards to the noise issues associated with the proposed car lift. The manufacture’s information on the proposed lift is as follows:

• Noise levels during operation under load, at 1m from lift doors = 55 to 60 dB (free-field sound pressure level)

• Noise level within the lift car during operation = 55 to 60 dB (free-field sound pressure level)

• Noise level within the lift motor room during operation under load = 55 to 60 dB (free-field sound pressure level)

7.50 The nearest residential windows at 1A Upham Park Road would be approximately 5m from the lift doors. At this point, it is noted that the rating level of noise would be 27 dB, 13dB below the background noise level.

7.51 Given the low levels of noise generated by the proposed vehicle lift, it is not considered that it would significantly impact on the living conditions of future residents of the scheme or adjoining neighbours. In addition to this in order to rest any outstanding concern, if Members were minded to grant approval, a informative would be recommended to ensure that a post-installation assessment of the car lift be carried out. The assessment should show that the operation of the car lift would not result in adverse vibration levels, as referenced in BS6472:2008 ‘Guide to evaluation of human exposure to vibration in buildings’.

Refuse

7.52 The applicant has discussed the proposed refuse and recycling facilities with the Council’s previous Senior Cleaning Supervisor who is happy with the proposed refuse and recycling layout. Refuse and recycling storage facilities would be provided at street level with the Council’s Cleansing vehicle being able to stop in a lay-by on Upham Park Road. Servicing to the building will also take place in this location.

Issue 7: THE IMPLICATIONS FOR TRAFFIC AND PARKING IN THE LOCALITY

7.53 Policy T.1.4 (Car and Cycle Parking and Servicing Facilities for Developments) of the UDP states that all developments must provide parking and servicing facilities in accordance with the Council’s standards as found in Appendix 3. The off-street car parking requirement for the commercial unit based on 1 space / 200m2, is 3 spaces. None has been provided. The maximum off-street car parking for the residential element is 11 spaces. The revised scheme includes a basement car park with space for 10 cars and 9 cycle spaces. The car park would be accessed via a car lift from Upham Park Road whilst bicycles could be transported via the main pedestrian lift which serves all floors including the basement.

- 23 -

7.54 The parking and servicing arrangements for the proposal have not

altered from the previously approved scheme. The Head of Traffic and Parking has previously assessed the proposal including the submitted Transport Statement, and has advised that the parking layout is satisfactory in terms of manoeuvring into and out of the parking spaces.

7.55 With regards to the lack of parking in association with the A1, A2 or B1 usage of the commercial area, there are some pay & display parking spaces near-by that will offer an opportunity for customers attending the shops to park.

7.56 The site is located in an area controlled by a CPZ with a heavy demand for parking. The five existing residential units on the site have residential parking permits. If the Council were minded to grant approval, a condition could be included to prevent residents from obtaining a residents parking permit in the area.

7.57 It is noted that 9 secure cycle spaces would be provided in the basement

for the occupants of the residential units.

Issue 8: ARE SUSTAINABLE BUILDING PRINCIPLES APPLIED

7.58 Sustainability underpins many of the UDP policies and the London Plan. These require developments not only to be sustainable in transport terms; but also to include appropriate recycling facilities and to minimise waste; to include energy efficiency measures and promote the use of renewable energy; and not to significantly increase the requirement for water supply or surface water drainage.

7.59 Policies ENV-B.1.1, ENV-P.1.3, ENV-P.2.1, ENV-P.2.4 and ENV-P.2.5 require that all developments should include recycling facilities and minimise waste, include energy efficiency measures, be sustainable in transport terms, promote the use of renewable energy and not significantly increase the requirement for water supply or surface water drainage.

7.60 The applicant has previously submitted an Energy Statement and has more recently submitted a report on how the developer would address the carbon emissions reduction condition on the previous application (Ref 00248/104-108/P3). The energy consumption and associated carbon emission of a ‘base case’ scheme that complies with Building regulations provide a good practice energy consumption benchmark.

7.61 The proposed scheme would incorporate low energy principles including at least the following energy efficiency measures:

• Low energy lighting

• Low U-Value double glazing

• High efficiency appliances.

- 24 -

7.62 The Energy Statement assesses the viability of a wide range of renewable energy technologies. An Air Source Heat Pump (ASHP) system and Solar Hot Water (SHW) panels to supply domestic water to residential units are the most feasible options and have been incorporated into the proposal.

7.63 The table below summarises the carbon savings and energy contribution calculated for the proposal.

7.64 The development would incorporate sustainable building principles, the efficient use of natural resources, minimise water, energy, fossil fuels while maximising the use of renewable resources, the proposal does not meet the 20% reduction in carbon dioxide emissions, and the Council’s Sustainability consultant is in discussions with the applicant on how to improve on the sustainability of the scheme. As such, a condition is recommended requiring details of the renewable technologies to be submitted to the Council for approval prior to works commencing on site (Condition 11).

8.0 PLANNING OBLIGATIONS

8.1 UDP policy IMP6.1 states that the Council will seek to ensure that a developer enters into a planning obligation to secure planning benefits

- 25 -

related to the proposed development. A payment or other benefit offered pursuant to a section 106 agreement is not material to a decision to grant planning permission and cannot be required unless it complies with the provisions of the Community Infrastructure Levy Regulations 2010 (regulation 122), which provide that the planning obligation must be:

(a) necessary to make the development acceptable in planning terms; (b) directly related to the development; and (c) fairly and reasonably related in scale and kind to the development.

8.2 Accordingly, it is mandatory that each criterion be satisfactorily addressed

prior to granting planning permission subject to a section 106 agreement. 8.3 The Council’s Planning Obligations SPD states that the exact type and

range of planning obligations, which may be sought for an individual site, will depend upon the particular circumstances and development proposed, and its impact upon the local environment, local services and facilities.

8.4 Whether or not planning obligations will be sought will be linked to the scale

and type of development. In terms of the Council’s SPD. The proposed residential component does not meet the 10 housing units threshold for planning obligations, nor does the commercial unit meet the 1000m2 floorspace requirement for commercial developments. Whilst the Planning Authority may consider that a mixed use scheme with a combined floor area in excess of 1000m2 such as this should require planning obligations, in this instance it is noted that the Planning Authority did not pursue any contributions on the previously approved development and it is not considered that any contributions would be warranted in this instance to mitigate against the impact of the proposal.

8.5 It is recommended that any approval be subject to a legal deed stating that

occupiers of the flats should not be eligible for parking permits within the CPZ. A considerate contractors agreement is also recommended.

9.0 EQUAL OPPORTUNITIES IMPLICATIONS

9.1 The equal opportunity implications of the proposal are discussed in the body of the report and, in particular, paragraphs 7.24 to 7.28.

10.0 CONCLUSION

10.1 The proposed minor changes to the development would not create a significantly different development from that previously approved (P2) and would not result in an unacceptable loss of employment land and, on balance, could make a positive contribution to the locality provided that the materials and workmanship incorporated into the development are of a high standard. The standard of accommodation provided is of an acceptable standard and subject to safeguarding conditions, the living conditions of neighbouring residents would be satisfactorily protected and the development would not significantly affect traffic and parking conditions in the locality.

- 26 -
