Register of self-build and custom-build

What is self-build and custom-build?

Self-build and custom-build housing is housing built by individuals or groups for their own use, either by building the home on their own or by working with builders.

Self-build projects are defined as those where someone directly organises the design and construction of their own home. This covers a wide range of projects, including a traditional DIY self-build home to projects where the self-builder employs someone to build their home for them. Community-led projects can also be defined as self-build.

Custom-build homes are where you work with a developer as an individual or a group to help deliver your own home. The developer may help to find a plot, manage the construction and arrange the finance for your new home. This is more of a hands-off approach, but your home will be tailored to match your individual requirements.

More information about self-build and custom-build is available on the self-build portal.

The current shortened register can be viewed below:

You may also find the National Custom and Self-build Association web site useful.

Why do we keep a register?

The Self-Build and Custom House Building Act 2015 places a duty on us to keep and have regard to a register of people who are interested in self-build or custom-build projects in the area. This register will help inform us of the level of demand for self-build and custom-build plots. The register consists of two parts: Part 1 and Part 2. 

We are required to grant sufficient planning permissions to meet the demand on Part 1 of the register within three years.

What is the difference between Part 1 and Part 2?

Part 1 of the register is for individuals and associations who meet the local eligibility criteria.

Part 2 is for individuals or associations who wish to register an interest, but do not meet the local eligibility criteria.

Further information on the eligibility criteria can be found in the guidance notes.

What planning policies do we have on custom and self-build?

  • Daventry Local Plan Part 2 was adopted in February 2020 and includes a policy requiring design codes for schemes at policy HO5
  • South Northamptonshire Local Plan Part 2 was adopted in July 2020 and contains within it at Part 4.6 a section on Self and Custom-Build Development and a Policy (LH5) which supports the delivery of Self and Custom-Built Homes
  • Northampton Local Plan Part 2 was adopted 23 March 2023 and includes Policy 14 which supports delivery of Self-build and custom build housing
