Residents fears over plan for 'mother of all basements'
Residents have raised objections to proposals for one of the largest basement developments in Kensington and Chelsea, west London.
Plans for the three-storey "mother of all basements" in Old Court House, Walton Street, Chelsea include a pool and ballroom.
The local residents' association said the knock-on impact would be "substantial" and "deplorable".
The architect, ABA, says it will not adversely affect nearby properties.
Garage and ballroom
The plan would involve extending underneath the house and part of the garden.
A three-car garage would be built on the lowest floor, a pool above it and a ballroom at the first subterranean level.
Kensington and Chelsea Council has yet to decide whether the application will be approved or recommend changes.
Conservative councillor Tim Coleridge said an estimated 1,300 truck journeys would need to be made to remove the earth.
The application states a traffic management plan has been devised which minimises disruption to residents.
It also says the digging out of the basement will not affect the structural stability of adjacent listed buildings.
