London service guide: Kitchen extensions.
Architects, Engineers, Surveyors & Builders Under One Roof.
Surveyor-led refurbishment advice via Hampstead Chartered Surveyors →One Studio. One Contract. One Team.
We deliver St John's Wood kitchen extension with kitchen designers, structural engineers and builders under one fixed-price contract - layout design, services, procurement, installation, finishes, Building Control coordination and handover through one accountable team.
Every kitchen extension project in St John's Wood is designed to respect the St John’s Wood Conservation Area and the character of stucco Italianate villas, Regency terraces, large mansion blocks. Our in-house RIBA architects handle Westminster planning applications, our chartered structural engineers specify any load-bearing work, and our directly-employed trades deliver the build under one fixed-price contract. We coordinate Building Control, Party Wall awards where needed, and all certifications through to handover.
Many kitchen extensions in St John's Wood involve removing internal walls (requiring structural engineering), extending into side returns or rear gardens, and creating open-plan living spaces. Our in-house kitchen designers, architects and engineers work together from day one.
Exclusive residential area within Westminster. St John's Wood conservation area features wide, tree-lined streets with substantial detached and semi-detached houses. Home to Lord's Cricket Ground and Abbey Road Studios.
A kitchen extension succeeds or fails on decisions that have nothing to do with brickwork: where the island sits, how far the cook stands from the table, whether morning light reaches the worktop. So we begin with the kitchen brief and let the architecture serve it — the drainage run for an island sink, the ducting route for extraction and the rooflight positions are all fixed on the drawings before any structural design starts. These are the calls we resolve first.
Six stages, kitchen decisions first, so nothing gets value-engineered mid-build.
Most kitchen extension builds run 10–16 weeks once on site. Read the full kitchen extension guide for layout options, glazing choices and programme detail.
The regulatory load on a kitchen extension is heavily service-driven: new cooking extraction must discharge correctly under the ventilation rules, relocated sinks need compliant drainage falls, kitchen circuits are notifiable electrical work, and large glazed openings must satisfy energy standards — all inspected and certified through building control, which we manage. The planning route itself depends on your street: consented, permitted development or conservation-area constrained. Check your borough’s position in our planning guide library.
A kitchen extension is really two projects — a build and a kitchen — and most go wrong where they meet. Ours are drawn by our in-house RIBA Chartered Architects with the cabinetry, structure and services on the same drawings, priced fixed on JCT terms, and built by teams we bring back project after project. RICS surveying support is available through our sister company where party wall or condition questions arise. Every contract carries £10M public liability cover, a 12-month defects period and a 10-year workmanship warranty. Call before 2pm on a weekday for a same-day response.
Kitchen Extension in St John's Wood typically costs £22,000–£55,000. The final price depends on the scope, specification and complexity of the project. We provide a detailed fixed-price quotation after the initial consultation and design phase.
