TOWN FABRIC

These two busy roads provides for the majority

of the vehicle circulation. Halswell town residentscan only go towards the city centre and Hornbyvia these two routes.Thus, traffic congestion can

become a major problem on these roads duringrush hour.

Major roads

Parks and reservesBuilding footprints

Minor minor roads Farm land

The building footprints consists mainly of

residential houses and are the result of suburbansprawl.They are well connected by the roadnetwork, however this had made residents very

reliant on car transportation.

Halswell is well populated with green lands.Ample

amount of parks and reserves are provided forresidents and visitors to enjoy.However, many ofthese spaces are overscaled and do not provide a

welcoming and cosy environment, becoming largedeserted spaces with no real purpose.

Lots of ugly new

subdivisionsgoing on at the moment.

Its kind of differentfrom the city, its

got its own feel, its own identity.

The buses donttend to run to where Ineed togoto work or recreation

Wedon'tyethavebuslanesoutthisway,sobusescannothavepriorityandareveryslowinrushhourtraffic.

Wedonthave greatshoppingor community facilities

and not manyplaces to work.Its generally not safefor children to

bike or walk to school duringcongested times.

Most people use their cars to get around and

there are problems with congestionatbusy times.

Suburb ofugly carparksandthose who use them don't pay any morefor them than those of us who don't.

Full of people who can't imaginegetting anywherewithout their cars.

We really need to find ways of helping peoplebe independent of

space hogging vehiclesthat consume oil and pump carbon dioxideinto the air.

The public transportwasnot too badbefore theearthquakes took out the City centre.

Its hard to get around the

supermarket...you alwaysknowsomebody;every aisle you go down you

know somebody.

There are successful,enthusiasticindividuals,groups, networks and liasons hardat work in the local area.

Notown centre.

A good active transport network

is something we dont really

haveat the moment.

EXISTING HOUSING TYPOLOGIES

Single unit detached houses are currently the biggest

form of long-term accommodation for Halswellresidents.Research shows they are predominantly3 bedroom homes with 2 car garages.However, theapartments also have 3 bedrooms, highlighting the lack

of 1-2 bedroom accommodation for smaller family types.

Most households are owned,but a large amount ofindividuals and couples rent.

Short residential years showsthat Halswell is a steppingstone for residents, and not along-term home.

A new housing typology needs to beintroduced in order to adapt to thechanging demographics of the Halswellcommunity.This typology shouldcomprise of 1-2 bedroom housing, withan aim to fulfill the needs of individualsand smaller families as they arecurrently neglected.

SITUATION AND RESULTS

SITUATION

Halswell lacks facilities suchas a town centre, retail,public meeting spaces, jobopportunities and housingtypology range.

No increase in facilities will lead toan increased demand for residentsto drive to their daily needs.Thus,increasing air pollution and trafficcongestion.

A slow and steady increase ofnew facilities around the town willstimulate the neighbourhood andprovide an even balance between theincreasing population and availablefacilities.

A sharp increase of new facilities withtoo many changes might exceed thenecessary amount for the populationgrowth.

The proposed solution is to grow the town centre insideout, whilst densifying the core.In order to do this, a

phase plan was implemented.The plan takes intoaccount population growth, and associates ammenitiesin proportion with the increased population.

INFILL HOUSING

EXISTING

The low density residential block lackscharacter and does not allow theopportunity for urban growth.

INFILL STAGE 1

A few voids between existing housesare infilled. This will stimiluate thecontinual development of a retail

street front.

INFILL STAGE 2

This process continues, whilstturning existing houses intostreet front retail.The infill beginsextending to the back of the site

and creates accommodationopportunities.

INFILL STAGE 3

Street front retail is fully developedand infill residential spreads furtherinto the back of the site, result is anincreased density.

The concept of infill looks at building upon existing usedland.Infill residential development does not require the

subdivision of greenfield land, natural areas, or primeagricultural land.Thus, helps preserves Halswellscharacteristics of greenfields and agriculture zones.

A series of primarily 1-2 bedrooms housing units areclosely packed to maximise this space and also targetssmaller household compositions such as individuals

and couples.

DEVELOPMENT PROCESS

The sites current buildings are single,

detached housing with external garages.

Its interesting to note the size of each plotof land (~800m2) and how little land the

building footprints use (~200m2).Longdriveways cut across these plots becausegarages are located behind the house.

DEVELOPMENT PROCESS

By focusing only on the perpendicular gridlines of the site, it allows us to see only thevoids that have the most potential to bereflected.

The voids are extruded at a sensible height

of 3 storeys.This forms the first stage of theprojects massing.

Buildings are pushed towards the centreand intersect with the public strip, creating

an integration between the buildings andthe strip.The result is an 8-11.5m widecentral circulation space between the newhousing.The width varies as you move

through the space, because the buildingfootprints are not consistently 8m apart.This effect of moving through a series of

choke points is created through reflectingthe voids.

The height of the houses are variedbetween 2 - 4 storeys.This visuallyenhances the housng typology.

DEVELOPMENT PROCESS

Staircases, vehicle access and entrance features are

implemented to allow all kinds of circulation through the site.

Public entrance to the new housing typology,located on the intersection bet ween Halswell

Road and Nicholls Road.

Public entrance to the new housing typology,located on Oakridge Street.

Access spaces within the s ite are sharedbetween residents only.Access to the first floor

and garage is through these shared spaces.

A shared underground garage is accessiblefrom the shared spaces linked between 3-5

houses.
