Pension Insurance Corporation has provided a £130m debt investment to Raven Housing Trust for the development of 630 homes across Surrey and Sussex.
Raven is set to deliver the new homes by 2026, with 58% to be social or affordable rent and 30% shared ownership.
Mark Baker, group executive director of finance at Raven, said: “We operate in an area of high demand, with high average house prices and high house price growth.”
