Design & Plan - Codes + Passports
The Design Code
An example of a design code is given in this downloadable PDF – Design Code for Custom Build Plots, but the following description will help you to understand this initially.
“A design code is a set of illustrated design rules and requirements which instruct
and may advise on the physical development of a site or area. The graphic and written components of the code are detailed and precise, and build upon a design vision such as a masterplan or a design and development framework for a site or area”
Design Codes are designed to be used by planners, developers and plot buyers. Any
development on CUSTOM self-build plots will need to adhere to such Design Code.
Typically they specify such things as the Masterplan, the Street Code, Building Height, Materials, Fenestration, and Detailing.
Buyers of individual plots and their design professionals have to follow guidelines set out in the Design Code with final approval being given by the local council.
The Design Code provides guidance that relates to individual plot arrangements and regulates how buildings should be located within their curtilage (‘Plot Area’). Advice and guidance also conveys how houses should sit in relation to adjacent neighbouring buildings.
The purpose of the Design Code therefore is to ensure a consistent and appropriate relationship between all neighbouring buildings.
The Plot Passport
Whereas the Design Code applies to the total development site, the Plot Passport aims to be a simple and succinct summary of the design parameters for a given plot. They add value by acting as a key reference point for the purchaser, capturing relevant information from the planning permission, design constraints and procedural requirements in an easily understandable and readily accessible format.
Most Plot Passports are between one and four pages long and form part of the marketing material available for the plot.
The passport clearly shows the plot location, the permissible building lines and side spacing requirements, proximity constraints to neighbouring buildings and the part of the site where a new house can be constructed (i.e. the developable footprint). There is usually also a building height restriction.
Passports are very clear about the number dwellings that can be built (generally only one) and any other pertinent details, including car parking and access location etc.
The choice of finishing materials, fenestration and roof shape may be left to the plot owner. Most are kept as simple as possible so that people can evaluate the various potential plots and work out which suits them best.

On carrying out a cost analysis and comparison between traditional and timber construction, the saving in using timber appears to be in the region of £2,700
