Extending a house in Holland Park is as much a planning and heritage exercise as a building one. Most of W11 sits within the Royal Borough of Kensington & Chelsea's conservation areas, and many of its villas are listed, so rear extensions, side returns and roof additions must be designed to preserve the character of a protected building and street.
We design extensions that win consent: rear and garden additions to the stucco villas and terraces, side-return infills, and roof or mansard space where the building and the conservation area allow. Each comes with structural engineering, party wall agreements with the neighbouring houses, and integration into the wider refurbishment of the home.
From feasibility and the planning application through to a finished, glazed, light-filled space, the whole project runs under one contract.
Conservation control, structure and the neighbours define what is possible in W11.
Holland Park, Ladbroke and Norland conservation areas tightly control extensions and external change — a careful, heritage-led design is essential.
Householder permitted-development rights are limited in conservation areas, so extensions almost always need a formal planning application.
Rear and side extensions to terraced and semi-detached villas trigger the Party Wall etc. Act 1996 — we serve notices and secure awards.
New openings, steel and large glazed elements are engineered in-house and detailed to perform within a period building.
