Self-build and custom housebuilding

What is self-build and custom buildhousing?

Ever wanted to design your own home? With a self-build plot you can take control and put a personal twist on design and layout of your dream home.

The Self-build and Custom Housebuilding Act 2015 places a duty on certain public authorities to keep a register of individuals and associations of individuals who wish to acquire serviced plots of land to bring forward self-build and custom housebuilding projects and to place a duty on certain public authorities to have regard to those registers in carrying out planning and other functions.

Types of self-build

Self-build housing refers to when an individual is directly involved in organising the design and construction of their own home. This can cover a wide range of projects, from a traditional DIY self-build home to projects where the self-builder employs someone to build their home for them. In this scenario, the finding and buying of a plot of land would usually be undertaken by the individual/self-builder.

Custom buildhousing

Custom buildhousing refers to an individual commissioning a specialist developer to help deliver their own home. In this scenario, the developer may secure the site and managethe build. They may even arrange the finance. This is a more ‘hands-off’ approach, but the home would still be tailored to match the individual requirements of the customer, who should retain primary input into the design of the dwelling.

Serviced plot

A serviced plot is a plot of land that either has access to a public highway and connections for electricity, water and wastewater, or can be provided within the duration of a development permission granted.

Join The Self-Build and Custom Build Register

What is the Self-Build Register?

We keep a register of people who are interested in carrying out their own self-build or custom build projects. This helps us understand the demand for such projects within our districts.

The Self-Build and Custom Housebuilding Guidance states 'Authorities can choose to work together to publicise and promote their registers and have a single application form provided it is clear which authority the application is being made to.'

Our self-build registers were created in October 2015.

How to join The Self-Build and Custom Build Register

When registering your interest, you are not making a commitment, the information is used to understand local demand.

To be eligible to register, you, or all members of the group/association an entrant represents, must be:

  • aged 18 or over
  • a British citizen, a national of an EEA State other than the UK, or a national of Switzerland
  • seeking (either alone or with others) to acquire a serviced plot of land to build a house to occupy as their sole or main residence

Registration does not mean that a suitable plot will be identified for you.

Where do you publish data on the supply of and demand for self-build plots?

We monitor the number of self and custom build plots that are granted planning permission each year.

Our Authority Monitoring Report (AMR) includes the number of individuals and associations of individuals on the register, as well as the number of plots secured through planning permissions which have either been restricted by planning condition or planning obligation, or have received a Community Infrastructure Levy Form 7 part 2 as demonstration of self-build status. 

How do you identify that a planning permission for self-build and custom housebuilding meets the legislative definitions?

We require evidence of self-build status within the planning application documents. For example:-

  • Does application form include self-build in description or is reference made in Section 17 of the form? 
  • Do the other application documents provide any indication of self-build?
  • Does the level of detail include how the applicant/client has had primary input into the layout/design?
  • Has a Unilateral Undertaking been submitted or does the Section 106 agreement include self-build obligations
