London will struggle to build its target 88,000 new homes every year for the next decade unless two major rail projects are given the green light, the deputy mayor for housing has said.

Tom Copley said the next London Plan would factor in the government’s request, which was part of a target for 1.5m new homes in the UK by 2029, but could fall short if enough infrastructure was not built.

He told the London Assembly Budget and Performance Committee that a “huge amount of infrastructure and funding” was needed.

“In order to actually get to that target, a lot of things have to happen,” he said. “The DLR extension is very important. We also need a Bakerloo Line extension, the West London Orbital.”
