What we deliver in Putney
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.
Side-return and double-storey extensions are the most popular, reclaiming narrow side paths and adding bedrooms. Wrap-around extensions create generous open-plan kitchens.
Dormer, mansard and hip-to-gable conversions depending on roof type; mansards are common on Edwardian semis in Upper Putney.
We replace older houses with modern family homes on wide plots, particularly near the river.

Common Putney questions
Things you might need to know about building in Putney.
Do I need planning permission for an extension in Putney?
Many extensions in Putney fall under permitted development. Where a full application is needed, it goes to Wandsworth 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 Putney 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 Putney?
Several streets in Wandsworth 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 Putney?
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.
