What we deliver in Wimbledon

Every street sits differently — a period terrace, a post-war semi, a modern infill. We shape the recommendation around your actual house, its planning context and how you want to live.

01 · House extensions

Rear and side-return extensions brighten dark Victorian houses and create open-plan kitchens. Two-storey extensions add much-needed bedrooms.

02 · Loft conversions

Dormer and mansard conversions suit Victorian terraces; hip-to-gable works well on 1920s homes.

03 · New builds

On large plots near the village or on corner sites, complete replacement of older bungalows with modern family homes is possible.

Common Wimbledon questions

Things you might need to know about building in Wimbledon.

Do I need planning permission for an extension in Wimbledon?

Many extensions in Wimbledon fall under permitted development. Where a full application is needed, it goes to Merton Council — we assess your property type, the council's restrictions and any conservation status on the first visit, and handle the application ourselves.

How long does a project in Wimbledon typically take?

From first consultation to handover: 6–9 months for a single-storey extension or loft, 9–14 months for double-storey or wrap-around. We give you a tighter estimate after the survey.

Are there conservation areas in Wimbledon?

Several streets in Merton Council's area fall within conservation areas that restrict materials and detailing. We check your exact address against the register on the first visit, and we have approved schemes in conservation areas nearby.

What is a typical extension cost in Wimbledon?

Build cost in this part of London runs £2,500–£4,000 per square metre for a finished extension including kitchen and finishes. Our calculator gives a personalised estimate.
