What we build in Upton Park
Most Upton 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 and Edwardian bay-fronted terraces, plus post-war and new-build estates.
Extension costs in Upton Park
A mid-spec 25 m² extension in Upton Park typically lands between £96,000 and £151,000 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 £2700–£4125 per m² depending on glazing, structural spans and kitchen spend.

Planning permission in Upton Park
One of the more permissive east-London boroughs for permitted-development rear extensions. Full applications go smoothly where design respects the terrace line.
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 Newham and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.
Party wall and neighbours
Standard terrace = two party wall notices; typically resolved cooperatively.
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 Upton Park 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 Upton Park
