Office fit out in Marylebone W1
Period buildings and mansion blocks run as offices and consulting rooms, where the fit-out is governed by the lease and the conservation area rather than by a fit-out guide.
What you are fitting out in Marylebone
Georgian and Victorian terraces, mansion blocks and purpose-built professional buildings, most of them long since subdivided into floors and suites. Offices sit over retail on the high street and Wigmore Street, and above consulting rooms on the medical streets. Very little of it was designed as an office and almost none of it as an open plan.
Professional practices, medical and consulting suites, family offices, and smaller businesses taking a floor rather than a building. The brief is usually cellular rather than open plan — rooms with doors, acoustic separation that actually works, and a reception that reads as a practice rather than a start-up.
The constraint that sets the programme
No goods lift in most of the stock, permit-controlled kerbside with short loading windows, and a communal entrance often shared with other tenants or with residents above. Material comes in by hand through a front door or a passenger lift, and a skip needs a licence and a bay suspension that may be refused. It is the Fulham access problem with central-London parking enforcement on top, and it is the reason a finish that arrives in tubs beats one that arrives on a pallet.
Who decides, and what needs consent
Westminster has 56 conservation areas and has removed permitted development rights in eight of them. It has also made an Article 4 Direction removing the permitted change of use from Class E — commercial, business and service — to C3 dwelling houses, so an office here cannot quietly become flats without planning permission. Check the authority before anything else: since 10 August 2026 the Oxford Street Development Corporation has been the local planning authority for the Oxford Street area, which runs along the southern edge of this district, and Camden’s transfer notice records that the borough is ‘no longer the Local Planning Authority’ for applications there. Internal fit-out is usually not a planning matter in any case — the consent that governs it is the landlord’s licence to alter, and on a listed building, listed building consent, which covers internal character as well as the elevation.
A fit-out normally answers to three separate things: your landlord’s licence to alter, building regulations where services or fire strategy change, and planning only where the outside of the building or its use changes. They run on different clocks and the licence is the one most often discovered late.
What we are usually asked for in Marylebone
- Cat B fit-out of a floor or suite in a period building
- Cellular offices and consulting rooms with real acoustic separation
- Reception and storage joinery made in our own workshop and fitted in sections
- Seamless floors laid over existing surfaces rather than breaking them out
- End-of-lease reinstatement on a demise with no service access
Partitions, joinery and glazing come from our own companies rather than a chain of subcontractors, which is why the timing and the warranty stay in one place. The low-waste method — refinishing over what is already there — is what makes most of this workable in an occupied building.
Can we fit out a Marylebone office floor with no goods lift?
It is most of what commercial work in W1 looks like, and the two things that decide it are how material gets in and what has to come out. Refinishing an existing floor rather than lifting it removes the waste side entirely and removes the phase that needs a skip licence and a bay suspension. What it costs is optionality — you are committing to a finish the existing substrate will carry — and on a period building that is usually the right trade.
A floor area cannot price a fit-out.
We walk the floor, look at what is already there and what can be kept, and tell you what the access regime does to the programme. Free, and it is the only honest way to put a number on Marylebone space.
