Design and build in Chelsea.
Chelsea is close to the studio. We design, price and build homes here, often below ground.
01The area
What a Chelsea house asks for.
Chelsea sits along the river, a short way from the studio in Fulham. We have built here for years, on townhouses and terraces.
The houses are mostly Victorian and Georgian terraces, often four storeys and sometimes five. Garden squares sit between them. A basement is a common ask.
Chelsea sits inside the Royal Borough of Kensington and Chelsea. Its basement policy, CL7, was adopted in January 2015. One storey only, and no more than half the garden.
Chelsea pricing runs open book on our own rate card. Expect a budget estimate within seven days, a cost plan next, then one contract.
