What we deliver in Fulham
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 rear extensions are Fulham's most-requested project — reclaiming the alley beside the kitchen to create a wide open-plan family room. Most fall under permitted development; we handle planning where it's needed.
Loft conversions are extremely common across Fulham's terraces — typically a rear dormer adding a master bedroom with en-suite. We design and build the full conversion in-house.
New-build opportunities are limited in Fulham, but we deliver replacement dwellings and infill plots where they come up.

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