Only 96 affordable homes were built in Plymouth last year. Council member Mark Lowry said the gap between construction cost and sale price is at least £50,000 per unit.
Plymouth built only 96 affordable homes last year, 37 of them for social rent, according to Local Democracy Reporting Service data. The city has 4,500 homes with planning consent that have not yet broken ground.
Plymouth City Council said it recognised it "needed to do better" but the economics have turned hostile. Cabinet member Mark Lowry told the scrutiny board that "it costs more money to build a home than it actually does to sell it." The gap runs at least £50,000 per unit, he said, meaning no developer will build unless the council or another party contributes that sum.
"The reality of the situation is it is unaffordable to build a home in Plymouth," Lowry said.
A council report described overall affordable housing completions as "flat with stalled development sites a continuing concern."
Andrew Crumplin, a builder and site manager who sits on the council for Reform UK, pushed back. "Everyone I know builds houses, it just seems like a problem for the council," he said. "I find it hard to believe that statement that you need to chuck £50,000 at a house to get a builder to build it." He added that spending £4 million extra on 80 homes at Bath Street and £6 million on Southway "seems ludicrous."
Daniel Steel, a Labour councillor, acknowledged the trajectory was off target. "We look like we are quite off track to what we should be," he said.
A £33.5 million scheme to build 135 affordable homes at Bath Street in Millbay, including 80 for social rent, has started construction with a £14 million contribution from Homes England. The government agency signed a memorandum of understanding with the council to accelerate building in the city.
The council has a vision of 10,000 new city-centre homes by 2026. Progress is being made on unlocking major sites including the former Southway Paper Converting Mill and mixed-tenure homes at Barne Barton estate.
Two hundred affordable homes are forecast for 2026-27, which the corporate plan monitoring report described as a "significant increase" on recent years. Armada Way is expected to house hundreds of them after Homes England acquired Congress Hall and neighbouring Mayflower House, which it plans to demolish and replace with tower blocks.
Affordable homes in the UK are let at least 20% below local market rents. Social homes run at roughly 50% of local rents for people on low incomes.
