What we build in Marylebone
We only offer services in Marylebone that suit its buildings and market. These are the projects we are asked for most here:
Clinic & medical fit-out
Clinic, dental and treatment-room fit-outs in Marylebone: hygiene-grade finishes, ventilation, specialist M&E, accessibility and the compliance documentation medical spaces need.
Office fit-out
Cat A and Cat B office fit-outs and refurbishments in Marylebone: 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.
Prime residential refurbishment
Prime residential refurbishments in Marylebone: whole-house and apartment refurbishments, structural alterations, extensions, M&E renewal, bespoke joinery and high-end finishes, managed discreetly with neighbours in mind.
Restaurant, bar & hotel fit-out
Restaurant, bar, café and hotel fit-outs in Marylebone: kitchens and extraction, bars, dining rooms, guest rooms, washrooms and back-of-house, planned around licensing, neighbours and your opening date.
Retail & shop fit-out
Shop and flagship store fit-outs in Marylebone: shopfronts, bespoke fixtures, lighting, stockrooms and tills, including live-trading refits where the store stays open while we work.
Planning, consents and site rules in Marylebone
Local authority: Westminster City Council. Before any design is fixed we check the planning and ownership position for your address, because in Marylebone this decides what is possible and how long it takes:
- Large parts of Marylebone are held by estate landlords, notably the Howard de Walden and Portman estates, each with its own consent process for alterations.
- The Harley Street area is dense with medical practices, so clinic fit-outs here often involve specialist ventilation, accessibility and compliance requirements.
- Westminster City Council applies conservation-area and listed-building controls across much of the area.
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 Marylebone
Do you fit out clinics on or near Harley Street?
Yes. We deliver clinic and treatment-room fit-outs, including the M&E, hygiene finishes and accessibility that medical spaces need. Medusa in Knightsbridge is an example of our clinic-and-spa work.
Do I need estate consent in Marylebone?
Often. Where the freehold is held by an estate such as Howard de Walden or Portman, you will normally need their approval as well as the council's. We manage both.
How much does a project in Marylebone 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 Marylebone 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 Marylebone project.
