Site operations

Gary, formerly director of GW Basements, has extensive hands-on experience in basement excavation, structural works and site logistics. He leads site operations, with particular experience on complex and heritage-sensitive London properties.

The company

From Victorian terraces to listed buildings.

We take on the structural side of a house: digging and building basements, underpinning walls, stripping out and putting in new structure, and building extensions and shells above ground.

The work ranges from straightforward Victorian terraces to listed buildings, including houses on the Grosvenor Estate. We work direct for homeowners, for developers and for main contractors who need a basement or structural package built.

Sister company

Extend Bespoke.

Extend Bespoke renovates and extends London homes, and shares its directors with us. On several houses we built the basement or the structure and Extend Bespoke finished the rest: Chipstead, Chiddingstone, Bowerdean, Howard's Lane and Vicarage.

A homeowner can come to either company. A developer or main contractor usually comes to us.

Office

320 Munster Road, Fulham.

Our office is in Fulham, SW6. We work on houses across central and south-west London, including Belgravia, Kensington, Chelsea, Fulham, Parsons Green, Putney and Chiswick.
