What we build in Stoke Newington
Most Stoke Newington 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 (De Beauvoir, Stoke Newington), Georgian terraces (Hoxton), warehouse conversions (Hackney Wick).
Extension costs in Stoke Newington
A mid-spec 25 m² extension in Stoke Newington typically lands between £124,000 and £184,000 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 £2975–£4550 per m² depending on glazing, structural spans and kitchen spend.

Planning permission in Stoke Newington
Hackney has stringent design guidance, especially around the many conservation areas (De Beauvoir, Clapton Common, Stoke Newington). Contemporary detailing is welcomed if it's sensitive to the terrace rhythm.
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 Hackney and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.
Party wall and neighbours
Almost every project needs two Party Wall Awards. Neighbours here are experienced — expect them to appoint their own surveyor.
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
Rear access via a side alley or garden gate speeds up muck-away and cuts labour cost noticeably.
Every quote we issue for Stoke Newington prices skip permits, parking suspensions, protection and welfare explicitly in the preliminaries — so the number you sign is the number you pay.
Value added in Stoke Newington
Well-executed extensions here tend to return a healthy share of their cost at resale, particularly where they add a genuine third or fourth bedroom.
