Kensington and Chelsea basement planning consent architect designed

Architecture for London has received planning permission for a large basement extension and refurbishment of a detached Edwardian house in the Royal Hospital conservation area of Kensington and Chelsea

This project was one of the first to be given consent by RBKC under the 2015 basement regulations.

The planning permission includes a full refurbishment of the ground and first floor levels of the house. A new basement extends under the entire footprint of the house and 50% of the garden. Basement accommodation will include a cinema and a gym with associated shower, steam and sauna room.

A concealed car lift to the front of the property creates parking for two cars underneath the front drive.


The house will be fitted with a combined heat and power boiler system and a rainwater harvesting system. These will reduce CO2 emissions and reduce water usage, whilst providing a continuous supply of water for irrigation purposes.

The complex planning submission to Kensington and Chelsea included a design, access and heritage statement and a construction methodology statement. Further reports submitted include basement impact and flood risk assessments, a tree survey and a construction traffic management plan.

A number of planning applications were submitted for various other elements of the project, and an application for a certificate of lawfulness was required for minor alterations to the existing windows to the front elevation of the house.

AFL worked closely with heritage and planning consultants at Savills London.
