We know that the large house builders benefit from scarcity of housing as it increases the prices they can charge for new builds. And as Paul Davies outlined, we've got a small number of very large builders who dominate the market. One method of increasing housing supply is self-build and self- managed build. Will the Government ask local authorities, outside the local development plans, to identify sites for five or fewer dwellings that can be either self-built or the building can be self-managed so that we bring houses into use, help small builders and help people become home owners?
