The first paper in CPRE's Housing Foresight series explores how the dominance of volume house builders is having potentially harmful impacts on the supply, location and design of new housing in England. It shows that greater support for small and medium sized house builders can help meet demand for housing and protect green spaces by delivering new homes - including through custom/self build - on smaller brownfield sites. The paper proposes four policy options: promoting small-scale brownfield sites; funding smaller builders; simplifying small applications; and the use of design codes.
