Place making through Design Coding

REAL

Structure of talk

1. Coding Considerations

• Why code?

• Types of code

• What to Code? – ‘Rules of Assembly’

2. Examples:

• Havant town centre

• Newhall, Harlow

3. Coding for local authorities

4. Check-list and pointers for Tottenham Hale study

Considerations

• Framworks and master plans

• Control of land

• Resources (time and money)

• Means of delivery

Why code?

• Different time frames

• By other people / disciplines

• Across different land ownerships

• Different political boundaries

• People change over time

Codes

• Need to communicate design vision

• Bring clarity and certainty as to requirements

Types of code

Two situations

1. Topic-based code

- design guidance

2. Form-based code

- the ‘working drawings’ of a masterplan

- regulating / co-ordinatingplan + code makes

clear which aspects of the masterplan are

mandatory

REAL What to code?

- ‘Rules of

Assembly’

REAL Neighbourhoods & connectivity

Neighbourhood centres

sited along the best

connected routes

REAL Streets

Streets aligned with

contours (or

perpendicular to

contours))

A clear street

hierarchy: primary

routes / secondary

streets / tertiary streets

• Width of street

corridors narrows

through centres

• Most important streets

have longest ‘straights’

REAL Squares and key buildings

Permeability increases

in and around central

areas

Greater continuity of

frontage along the

more important routes

Squares located at the

intersection of the most

important routes

Public buildings are

located on the most

important streets, often

set back from the street

REAL Street / building rules

Buildings address the

street

Taller buildings (and

greatest densities)

along the highest

footfalls

Prominent sites attract

landmark buildings

REAL Street / building rules

• Buildings on street

corners have the

principal elevation to

the more important

street

• Front doors are located

against the more

important street

REAL Land uses

The best connected

attract land uses

needing high footfall

(shops and services)

The least well

connected streets

attract uses such as

family housing

Level 1: Urban structure (2D)

• Street pattern / connections

• Street hierarchy

• Street alignments

These effectively also determine land use and density

Level 2: Massing (3D)

• Street section

• Building frontages

• Building heights and envelopes

• Plot Series These effectively also determine entrance positions, relationships between indoor space,

private space and the public realm

Level 3: Detail Codes

• Colour / materials palettes

• Architectural detail (not)

• Streets and public realm

Check-list

1. Design and delivery – two sides of same coin

2. Be clear whether codes are to be generic or

relate to a regulating plan

3. Codes must be:

• Concise & capable of being measured against

• Technically competent

• Explain the reason for the code (vision)

• Offer a procedure to consider an alternative

4. Be clear about levels of prescription

• Urban structure (level 1L)

• Massing (level 2)

• Architectural / public realm detail (level 3)

REAL

Tottenham Hale site:

What are your priorities -

• 3 must- deliver objectives?

• 7 nice-to-have ideas?
