London Borough of Westminster

Architects in Westminster

A RIBA chartered practice based in Dulwich, working across Westminster. A tightly controlled planning environment where heritage experience and a well-evidenced application are essential.

Architects working across Westminster

Westminster has one of the most demanding planning environments in the country: a very high proportion of listed buildings, conservation areas covering most of the City, and detailed policy on everything from basements and rear extensions to plant, glazing and external alterations.

We work across the City, from Marylebone and Fitzrovia to Pimlico, Belgravia, Bayswater and St John's Wood, on apartment and townhouse refurbishments, listed building alterations and commercial fit-out. Marjoram Architects is a RIBA chartered practice with its studio in Dulwich, and every commission starts with a free initial consultation.

Planning in Westminster

Detailed policy, carefully navigated

Westminster applies its policies closely and expects a well-evidenced case. We establish the route and the constraints before design work begins, and use pre-application advice on sensitive proposals.

Listed buildings and conservation

Consent as well as permission

Most of the City sits within conservation areas and a large share of buildings are listed, so alterations typically need listed building consent alongside planning permission. We prepare the heritage material and deal with conservation officers directly.

Common Project Types

Refurbishment and alteration

Whole apartment and townhouse refurbishments, internal reordering of listed interiors, rear and roof alterations where policy allows, and commercial fit-out and retrofit.
