In 2022-2023, there were 25,000 affordable homes built and last year just under 4,000 were built, according to City Hall figures.
The mayor said: “Homes being built in London have dried up and it’s a nationwide problem.
“I’m not willing to stand by when that happens and so working with the government we’ve announced today a temporary short-term package of emergency measures to kickstart house building in London, which means more affordable homes that Londoners desperately need.”
In a release, City Hall said that the scale of the housing crisis in recent years means “emergency action is needed to get building moving”.
The government said that a “perfect storm due to a combination of spiralling construction costs, high interest rates, the legacy of the previous government, impact of the Covid-19 pandemic, regulatory blockers and wider economic conditions,” had created an urgent need for more housing.
