Builders in Westminster

The residential heart of Westminster includes early Georgian terraces around Smith Square, Lord North Street and Cowley Street, together with Edwardian mansion blocks and later apartment buildings. The Georgian houses have narrow plans, fine staircases and panelled rooms, but kitchens, bathrooms and services often need complete renewal.

The challenge is to create a comfortable modern home, with better kitchens, bathrooms, storage and heating, while respecting interiors that are often of real historic importance.

Most of our work in Westminster is refurbishment and restoration rather than new space:

• A full refurbishment of a townhouse or flat: a better layout where the building allows, new services, kitchen, bathrooms and finishes. See our house refurbishment cost guide and flat renovation cost guide.
• Period and listed interiors: panelling, staircases, cornices and joinery repaired, or matched where they must be replaced. See period home interiors and coving, cornices, skirting and doors.
• Joinery made for the room: see bespoke joinery in London.
• Rear and roof level additions where planning allows: our guide to planning a house extension sets out the order.

Before any of it, the free design cost calculator shows what the design, engineer, council and party wall fees come to.

Typical London jobs priced on our estimator in October 2026, indicative rather than a quotation:

• A two bed flat of about 75 m², refurbished at a Standard finish: £112,800 to £148,200 with VAT.
• A one bed flat of about 45 m²: £71,000 to £95,000 with VAT.
• A whole house refurbishment that includes a new extension: £1,100 to £1,350 per square metre of floor worked on, ex VAT, at a standard specification.

Work to a listed interior and the restoration of original joinery are priced from a survey of the building. The free estimate gives a first range for your own home in two minutes.

This part of London lies within the City of Westminster and is covered by conservation areas, and many of its Georgian houses are listed. Listed building consent is required for works affecting a listed building's character, including internal alterations, and external changes are closely controlled.

We establish the consents your project needs at the start, prepare detailed drawings and specifications, and plan the work so that historic fabric is protected throughout.

In Westminster we refurbish and restore period townhouses and apartments, renew services discreetly, create new kitchens and bathrooms and design bespoke joinery that suits historic rooms. Where planning allows, we also carry out rear and roof-level alterations.

Security, access and traffic restrictions near government buildings mean logistics must be planned carefully, and we agree arrangements before work begins.

Close by in Pimlico, on Balniel Gate, we designed and built a home around a new layout that merged two rooms into a single open space, creating a generous entrance, living area and separate sitting room, with herringbone flooring throughout. It shows how a thoughtful plan can transform a period home in SW1.
