The tool aims to help self builders, local authorities, and consultants understand the demand and supply for custom and self-build homes in their area. The data is updated yearly and is published by central government here - Self-build and custom housebuilding data. NaCSBA has developed a Darft Standard Methodology for assessing demand for custom and self-build homes. The white paper for this methodology can be downloaded here - NaCSBA Standard Methodology White Paper. The data below has been calculated using this methodology.
