What we deliver in Farnham
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.
Rear and side extensions add space to Farnham's period and suburban homes; in the conservation areas we design sympathetically and handle the consent end-to-end.
Loft conversions add bedrooms without altering footprints — a good fit for Farnham's period houses where extending out is constrained.
On suitable plots beyond the protected centre, we deliver replacement dwellings and new-builds, managing design and consents in-house.

Common Farnham questions
Things you might need to know about building in Farnham.
Do I need planning permission for an extension in Farnham?
Many extensions in Farnham fall under permitted development. Where a full application is needed, it goes to Waverley Borough 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 Farnham 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 Farnham?
Several streets in Waverley Borough 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 Farnham?
Build cost in this part of Surrey runs £2,500–£4,000 per square metre for a finished extension including kitchen and finishes. Our calculator gives a personalised estimate.
