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.

Common questions
Working with Marjoram in Westminster
-
Yes. We design residential and commercial schemes across the City, including Marylebone, Fitzrovia, Pimlico, Belgravia, Bayswater and St John's Wood. Every project starts with a free initial consultation.
-
Yes. Heritage and conservation work is one of our core areas. In Westminster most alterations to a listed building need listed building consent as well as planning permission, including internal work that would not normally be controlled. We prepare the heritage statement and consent applications and manage the conservation officer relationship.
-
Everything from a single-storey extension to whole house renovations, one-off houses and multi-unit residential and mixed-use schemes. We are a small studio, so the people you meet at the outset are the people working on your project throughout.
-
Fees are agreed in writing before we start and are set against defined work stages, so you know what each stage covers and what it costs before committing to it. The right structure depends on the size and type of project, and we set out the options at the initial consultation.
-
Once an application is validated, householder and minor applications are generally determined in around eight weeks, and larger schemes in around thirteen. Design work and preparing the application come before that, so it is sensible to allow several months from first meeting to decision.
-
We visit the property, discuss what you want to achieve, and set out the likely planning route, the scope of work involved and a realistic budget. There is no obligation to proceed.
