RenKap aims to deliver an online platform where housing associations and local authorities can upload their unused small sites.

Via the platform, RenKap will review, procure and manage the delivery of high-quality homes, with builders and off-site manufacturers bidding to deliver them.

“Small sites are built more quickly and are already part of our communities,” said Richard Beresford, chief executive at the National Federation of Builders (NFB).

“They are also delivered by SMEs, who train around 80% of construction apprentices and employ within 15 miles of their head office.

“They help the industry grow and deliver more sustainable employment.

“We need more of them.”

Rico Wojtulewicz of the House Builders Association, added: “Local authorities have resisted many attempts to get more small sites delivered.

“Any opportunity to get an increased number of them through planning is a major step forward in solving the housing crisis.”
