Khan told a recent London First event said that he would instead concentrate on the level of affordable homes within new housing developments.
The Labour candidate said that he would prioritise housing for Londoners and pledged that 50% of new homes will be allocated as "genuinely affordable". Khan also proposed revising the London plan to reflect this.
Khan emphasised the importance of affordable housing by stating that he would rather build fewer homes overall if it meant that a greater number of affordable homes were constructed.
Both the Labour and Conservative candidates have highlighted the issues of housing and affordable housing in London. Khan has previously stated that he would use the affordable homes budget to "support housing associations in their plans to ensure a minimum of 80,000 new homes a year."
According to a recent interview with The Economist, Khan said that building on London's green belt is not the solution the capital needs to solve its housing crisis.
The Conservative candidate, Zac Goldsmith listed housing as a number one priority for the capital. He pledged to double "home building to 50,000 a year by 2020 and ensuring development is in keeping with the local area" following his 'Londoners first' rule.
