Welcome to the construction website for the redevelopment of our sites at 40 & 63-81 Pelham Street.

In November 2021, our proposals to redevelop the two sites were approved by the Royal Borough of Kensington and Chelsea (RBKC).

The approved plans will replace the existing building at 63-81 Pelham Street with exemplary office space and upgrade the public realm in front of the building with wider, more generous pavements. At 40 Pelham Street, our plans will bring the vacant site back into use with modern office space and a publicly accessible garden courtyard.

We are committed to delivering these developments sensitively and with respect to our neighbours.
