What we build in Maida Vale
Most Maida Vale 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. Grade-II stucco terraces, mansion blocks and mews houses — many in conservation areas.
Extension costs in Maida Vale
A mid-spec 25 m² extension in Maida Vale typically lands between £136,000 and £206,000 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 £3250–£4950 per m² depending on glazing, structural spans and kitchen spend.
| Project | Size | Maida Vale all-in |

| Full-width rear | 20–30 m² | £136k – £206k |

| Double-storey rear | 40–60 m² | £265k – £402k |
Planning permission in Maida Vale
Westminster City Council is one of the strictest in London. Article 4 removes many permitted development rights; expect a full householder application and heritage-officer consultation for anything visible from the street.
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 Westminster and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.
Party wall and neighbours
Terraced and mansion-block context means a Party Wall Award is effectively guaranteed, often with two adjoining owners.
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
Tight on-street parking means bay suspensions and timed deliveries — your builder should price this, not absorb it.
Every quote we issue for Maida Vale 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 Maida Vale
Light and layout move value here more than raw square metres — spend on glazing and ceiling height.
