National Model Design Code Glossary

Area type

Parts of the local area that share common features and characteristics.

For example, a suburban area type might bring together a number of different housing estates with common densities, heights, building line, party wall condition etc, under the umbrella term “outer suburbs”.

Common rules and parameters can then be applied to the “outer suburbs” area type in the design code.

Example area types are provided in the National Model Design Code, but in practice area types should be defined locally

Area type matrix

A table detailing the elements of the design code that are likely to differ between area types.

Area type worksheet

A set of prompts and sections to be completed, detailing the key elements and features that should be considered when undertaking a character study. This is not an exhaustive list and should be adapted locally.

Character study

A process of analysis at area type level to determine the elements and features that contribute to the unique character of a place. This process can be used to determine existing area types, using the area type work sheet.

Coding plan

A plan at local authority level showing the local areas to which a code will apply. The coding plan can show:

  • Existing built-up areas
  • Landscape designated areas
  • Heritage areas
  • Protected open space
  • Special policy areas
  • Development areas

Context study

A mapping exercise detailing spatial information about the area surrounding a site. A suggested list of information that could be included is provided within the context section of Guidance note: code content.

Design code

A set of illustrated design requirements that provide specific, detailed parameters for the physical development of a site or area. The graphic and written components of the code should build upon a design vision, such as a masterplan or other design and development framework for a site or area.

Design guide

A document providing guidance on how development can be carried out in accordance with good design practice, often produced by a local authority.

Design vision

A clear articulation of what an area should be like in the future, developed with the local community. Local planning authorities may wish to create a vision statement setting out specific aims of the design code.

Development area

Parts of the local area where radical, rather than incremental change is planned. These might include regeneration areas where significant change is expected to the existing urban form, urban extensions and new settlements.

Framework plans

A set of plans at local area or settlement level that detail spatial information, for example, street hierarchy, transport accessibility, open space, land use and patterns of built form.

Historic study

A mapping and research exercise detailing historical information about the area surrounding a site. Suggestions about information that could be included is provided within the context section of Guidance note: code content.

Site study

A mapping or diagrammatic exercise, detailing spatial information about a site and its immediate surroundings. A suggested list of information that could be included is provided within the context section of Guidance note: code content.
