This report analyses why small sites are not playing a more meaningful role in the UK’s housing delivery. Based on a sample of 60 developments across London, 10% of the small sites granted planning permission in the Capital in the last three years, it considers the journey of developments on small sites through planning and the constraints and challenges that they encounter.

As the Government looks to reform the planning system, increase housing delivery and increase the role of urban land, the research and its findings have nationwide relevance and provide the evidence to help inform discussions on planning reform.
