As director of the unit he will steer a £2bn programme that involves the HCA taking direct action to build homes on surplus public sector land.
Rather than sell land directly to the market, the HCA will enter into partnerships with developers through the unit imposing robust contractual conditions to deliver housing schemes.
The Government hopes this will increase the pace of house building and diversify the market by supporting smaller builders and modern methods of construction.
Kinsella has a track record in delivering major housing developments on public land, having spent the last 11 years as the Growth and Partnerships Director at Barratt Partnerships, the house builder’s national public sector team.
He said: “I am excited by this opportunity to create a new delivery model for housing supply and increase innovation in the sector.
“The major housebuilders have a huge role to play in increasing supply but it is clear to me that Accelerated Construction and other HCA-backed initiatives are essential to diversify the market and ensure we can meet the pent-up demand for housing in this country.”
He will report directly to HCA chief executive Nick Walkley, who said: “This is a very important appointment for the agency. Stephen is a private sector housebuilding leader with a comprehensive understanding of developing on public land.
“He will bring strong leadership skills, extensive industry knowledge and a track record for doing things differently.”
