What we build in Tufnell Park
Most Tufnell Park projects we scope fall into three buckets: a side-return or rear infill that fixes a dark galley kitchen, a full-width rear extension that opens the ground floor to the garden, and a rear-plus-loft package that adds a bedroom while the scaffold is already up. Victorian terraces, Georgian townhouses, Hampstead villas and 1960s ex-LA stock.
Extension costs in Tufnell Park
A mid-spec 25 m² extension in Tufnell Park typically lands between £126,000 and £191,000 all-in — that figure includes professional fees, planning and Building Control, party wall, a 12% contingency and VAT at 20%. Ex-VAT build rates run £3150–£4800 per m² depending on glazing, structural spans and kitchen spend.

Planning permission in Tufnell Park
Camden's conservation-area coverage is heavy in Hampstead, Primrose Hill and Fitzrovia. Rear extensions to 3m PD are often possible outside these zones but the planners scrutinise glazing and roof form closely.
Before you assume permitted development applies to your street, check whether your street falls inside a conservation area or an Article 4 direction — both are common in Camden and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.
Party wall and neighbours
Terraces mean two Party Wall Awards on almost every project.
Serve notice at least two months before you break ground. Budget £1,200–£2,400 per adjoining owner if they dissent and appoint their own surveyor — see the Party Wall Act guide.
Access, logistics and site set-up
Narrow roads limit lorry size, so materials arrive in smaller loads; a good programme allows for it.
Every quote we issue for Tufnell Park prices skip permits, parking suspensions, protection and welfare explicitly in the preliminaries — so the number you sign is the number you pay.
