A councillor in Bromley is trying to build flats in Sadiq Khan's garden to encourage him to adopt his own London Plan.

Cllr Simon Fawthrop has applied to Wandsworth Council to build a three storey flat block in Mayor Khan's back yard.

The Petts Wood councillor said he wanted to show the Mayor the damaging effect his planning bible would have on parts of suburbia.

Petts Wood is an area of Special Residential Character, something Cllr Fawthrop says is at risk because of the ambitious London Plan.

He said: “Before he starts allowing unrestricted building in my residents back gardens he should start with his own back yard.

“Mayor Khan’s top down one size fits all policy will devastate one of London’s two premier garden suburbs, which has been designated an Area of Special Residential Character."

He said gardens in Petts Wood come under threat due to "unrestricted developments".

The draft policy encourages small developments within 800m from train stations and town centres "within the curtilage" of an existing houses.

According to City Hall, removing density limits would boost the number of homes near town centres and transport hubs.

Under Khan’s draft London Plan, which sets a framework in the capital, 66,000 homes should be delivered a year, compared to the current rate of 29,000.

Half of those need to be affordable, defined as being rented for no more than a third of average earnings, or under shared ownership.

Cllr Fawthrop has proposed one flat and two maisonettes in the Mayor's garden in Streatham.

A spokesperson for the Mayor of London said: “Rather than pointless political stunts, Councillor Fawthrop should spend their time and energy encouraging Bromley Council to build the new genuinely affordable and social homes that local residents and Londoners desperately need.

"Sadiq makes no apologies whatsoever for making this a top priority for his administration."

According to the Mayor's housing targets for small sites, Bromley needs to deliver 10,290 in the next ten years.

The London Plan aims to tackle the capital's housing crisis, which according City Hall has a generation left unable to afford rent or a mortgage.
