Self-build and Custom Housebuilding viability guidance

Released On 5th Jan 2024

The viability of development can be a source of dispute between local authorities and developers – when this includes Self-build and Custom Housebuilding, differences can be magnified - with no national guidance on how to deal with the viability of Custom and Self-build housing.   Three Dragons, working with the Right to Build Task Force, has recently published guidance to fill the gap in the Planning Practice Guidance.  The new industry guidance sets out the principles behind modelling the viability of Custom and Self-build housing and then the variables needed for accurate modelling of this housing type.  For example:

• The premium on values;
• The additional costs of building
• Professional fees that should be used.

The guide will be particularly useful for local authorities and viability practitioners in assessing the viability of local plan policies.

The guidance can be found alongside other guidance notes on Custom and Self-build housebuilding on the Right to Build Task Force website and is also available here.
