Only half of Londoners are open to more homes being built despite the housing shortage, a YouGov poll from business campaign group London First found.
At the same time two thirds (66%) said the government is not spending enough time addressing the issue and three quarters (74%) think there is a housing shortgage in the capital.
Jasmine Whitbread, chief executive of London First, said: “The falling number of people ready to welcome new homes in their area is a concern, particularly given we know that housing remains a priority for Londoners.
“Our research shows an additional £8.6bn of investment must be unlocked if we’re to meet the London Plan target of building 66,000 new homes a year.
“As well as getting the funding in place, we also need to persuade Londoners that new housing will benefit the places they live in.”
