Fit-Out & Refurbishment Contractor in Mayfair
Mayfair packs Georgian townhouses, headquarters offices, flagship stores on Bond Street and Savile Row, hotels and some of London's best-known restaurants into a few hundred acres. Almost every building is listed, in a conservation area, or both — and much of the freehold sits with estate landlords.
We are a London-based design and build contractor, founded in 2016, with our office on Buckingham Palace Road. One team takes your project from survey, design and consents through construction to handover — with around 70% direct labour, ISO and CHAS accreditation, a 4.9★ Google rating and every project to date delivered on budget and ahead of programme.

What we build in Mayfair
We only offer services in Mayfair that suit its buildings and market. These are the projects we are asked for most here:
Office fit-out
Cat A and Cat B office fit-outs and refurbishments in Mayfair: layouts, partitions, ceilings, lighting, M&E, data cabling, kitchens, meeting rooms and furniture, delivered around your lease dates. We work to landlord fit-out guides and schedule noisy work out of hours when the building is occupied.
Retail & shop fit-out
Shop and flagship store fit-outs in Mayfair: shopfronts, bespoke fixtures, lighting, stockrooms and tills, including live-trading refits where the store stays open while we work.
Restaurant, bar & hotel fit-out
Restaurant, bar, café and hotel fit-outs in Mayfair: kitchens and extraction, bars, dining rooms, guest rooms, washrooms and back-of-house, planned around licensing, neighbours and your opening date.
Prime residential refurbishment
Prime residential refurbishments in Mayfair: whole-house and apartment refurbishments, structural alterations, extensions, M&E renewal, bespoke joinery and high-end finishes, managed discreetly with neighbours in mind.
Clinic & medical fit-out
Clinic, dental and treatment-room fit-outs in Mayfair: hygiene-grade finishes, ventilation, specialist M&E, accessibility and the compliance documentation medical spaces need.
Planning, consents and site rules in Mayfair
Local authority: Westminster City Council. Before any design is fixed we check the planning and ownership position for your address, because in Mayfair this decides what is possible and how long it takes:
- Most of Mayfair lies within the Mayfair Conservation Area, and a large share of buildings are listed, so internal works can need listed building consent as well as planning.
- Much of the area is held by estate landlords such as the Grosvenor estate, so a Licence for Alterations and the estate's own design approval usually sit alongside council consents.
- Westminster City Council controls hours of noisy work, deliveries and skips closely; we plan logistics around them from day one.
We prepare the drawings and statements, submit the applications and build the approval time into your programme — so construction starts on a date you can rely on.

Most contractors avoid numbers. These are real Craftex projects — total value, size and time on site — so you can benchmark your budget. Your cost will depend on condition, specification, consents and access; we confirm it in a unit-by-unit cost plan.

Questions about building in Mayfair
Do I need listed building consent for an internal fit-out in Mayfair?
If the building is listed, yes — listed building consent covers internal alterations too, not just the facade. We check the listing and conservation status in our first survey and build the consent route into the programme.
Can a Mayfair shop or office stay open during works?
Usually, yes. At Drake's on Savile Row we refitted the flagship over 12 weeks while it kept trading, by phasing the works and doing noisy activity outside trading hours.
How much does a project in Mayfair cost?
It depends on scope, condition, specification and access, so we don't publish a price per square foot without seeing the building. As a reference, the table above shows what recent Craftex projects actually cost. Our Feasibility & Costing Study gives you a detailed, unit-by-unit cost plan before you commit.
How long will my Mayfair project take?
Programme depends on size, consents and whether the building stays occupied. Our projects have ranged from three weeks for a 750 sq m office refurbishment to seven months for a £2.2M conversion. We give a realistic programme with the cost plan, and every project we have delivered so far has finished ahead of programme.
Who handles consents with Westminster City Council?
We do. Our design and planning team prepares drawings, applications and method statements, and manages planning, listed building consent, building control and landlord or estate licences alongside the build programme.
Do you use subcontractors?
Around 70% of our labour is direct, and one Craftex project manager controls every trade. That gives you one accountable team, consistent quality and no gaps between designer and builder.
What is the minimum project size you take on?
We typically take on projects from around £100k, from single floors and units to whole buildings.
How do I start?
Send us the address, a short description and any drawings or photos. We arrange a site visit, then prepare a Feasibility & Costing Study with design options, consents, a cost plan and a programme for your Mayfair project.
