Designers, Architects, Engineers & Builders Under One Roof.

One Studio. One Contract. One Team.

Kitchens here are often in Italianate villas or in the Victorian, Edwardian and interwar mansion blocks that run through the centre of St John's Wood. Altering a leasehold flat may need the landlord's permission, and a listed house comes under City Plan Policy 44's protection of original detail and historic fabric, so we settle both before the layout is drawn.

Start a mansion-flat kitchen with the lease. According to LEASE, its terms may mean the landlord has to give permission before you alter anything, and that remains true when planning permission or building regulations approval has been granted. Even where alterations are allowed, another clause can restrict the work: a requirement that floors are carpeted might prevent a wooden or laminate floor running through a kitchen-diner.

Listing brings in City Plan Policy 44, under which work to a listed building should keep its special interest, protecting its original or significant detail and historic fabric and restoring them where that is appropriate. So we check the listing before placing a new extract duct, a soil run or a wider opening between kitchen and dining room; Westminster's mini guide counts some 470 listed buildings in the St John's Wood conservation area.

Villa kitchens and mansion-flat kitchens

St John's Wood was built up in the 1820s and 1830s, largely on land owned by the Eyre family, as the first example of suburban residential development in Inner London. Westminster's audit describes its houses as generally two or three storeys over a basement in large plots, with the villa design adapted to semi-detached buildings that were often made to resemble one large property.

In a villa we trace the drainage and extract route from the kitchen to the outside before cabinetry is drawn, and in a semi-detached pair we check whether a new opening or beam meets the party wall. In a mansion flat we agree with the managing agent where the kitchen can connect to the shared stacks and when long or heavy items can use the lift.

Where the kitchen goes in a villa

In a St John's Wood villa the kitchen may sit on the lower ground floor, on the raised ground floor at the back, or in a later rear extension. Each has trade-offs: the lower floor reaches the garden but needs daylight and a safe stair; the ground floor is close to the dining room but may be smaller.

We draw each option with its drainage route, its extract route and its link to the garden, so the choice is made on what the house allows rather than on a preference for one floor.

Opening up a mansion-flat kitchen

Many mansion flats have a narrow kitchen with small service rooms behind it. Taking out the partitions between them can make a kitchen with a dining table, provided the walls are not structural and the lease allows it.

LEASE says the landlord's permission is needed where the landlord owns structural walls to be knocked through, shared floors or ceilings that underfloor heating would pass into, or the chimney and flues.

So the survey records which walls carry the floors above before any opening is drawn.

Extraction, gas and drainage

LEASE counts moving radiators and changing gas pipes or electrical wiring among alterations, alongside structural work.

A cooker hood needs a route to the outside: through an external wall, up an existing flue, or by recirculation where neither is possible. In a block, the route and any grille on the front need the landlord's agreement, and in a listed villa they may need consent.

Sinks and dishwashers are placed where their waste can fall to an existing stack. If an island needs a sink, we check the floor build-up for a pumped or gravity waste before the island is fixed.

Stone, timber and the room around the kitchen

Worktops in stone or composite are templated after the base units are fixed and delivered in pieces sized for the stair or lift. Timber fronts are painted or lacquered in the workshop, so only touching-up happens on site.

Where the kitchen shares a room with original cornices, shutters or a chimneypiece, the cabinetry stops short of them and is scribed to the walls rather than fixed into old plaster.

Bringing stone and cabinets to a St John's Wood door

Worktop slabs, tall units and a skip all need room at the kerb. Westminster lets you apply to suspend a parking bay outside for a skip delivery or building works, with 10 working days' notice, and separate licences are required before a skip, scaffold or hoarding goes on the public highway.

If a skip or heavy plant would stand over a vault beneath the pavement, the construction code calls for careful consideration of that structure first. Level 4 jobs, the ones outside the code's other levels, have no formal requirement to agree working practices and a communication strategy with the council, yet they are still meant to follow its principles, and Westminster wants every contractor to respect its spirit on working hours, limiting disruption and keeping neighbours informed.

For made-to-measure cabinetry, panelling and fitted storage, see our St John's Wood bespoke joinery service: the same joinery team draws and builds it.

From survey to installation: a St John's Wood kitchen

Once we have visited, we survey the room and its drainage, power and extract routes, and check the listing and, in a flat, the lease. With that known, our in-house designers and architects plan the kitchen within what the building and its consents permit, while our in-house structural engineers work out any new opening.

A written quotation comes when the scope and consent route are agreed, and fitting is timed around the joinery, stone and appliance deliveries. No deposit is required.

Kitchen renovation in St John's Wood: questions

Can I move the kitchen in a St John's Wood mansion flat?

Possibly. LEASE warns that a lease can require the landlord's consent for alterations regardless of any planning or building regulations approval, so we read the alterations clause and ask the managing agent about the shared drainage before fixing the layout.

Does a new kitchen need building regulations approval?

Not always. Gov.uk does not require approval for replacing a sink, for most repairs and replacements, or for new power and lighting points, but work on a heating system, a fuse box or glazing units is not exempt.

Can I open the kitchen into the dining room in a listed villa?

It may be possible. Policy 44 of the City Plan is there to preserve a listed building's special interest and its historic fabric, so we record the cornices, doors and joinery the rooms keep before the opening is drawn.

When can kitchen fitters work and deliveries arrive?

Westminster permits building work from 8am, until 6pm on weekdays and until 1pm on Saturdays, and its Code of Construction Practice says all construction traffic must keep to the agreed site working hours unless the council agrees otherwise.

Can I take out the wall between the kitchen and the service rooms in my flat?

Possibly. LEASE says the landlord's permission is needed where the landlord owns structural walls to be knocked through, so we confirm the wall's structure and the lease first.

What does a kitchen renovation in St John's Wood cost?

For a St John's Wood kitchen the main costs are in what surrounds the units: whether the lease or an estate licence allows a wall to move, how extract and waste reach the stack or an outside wall, and how worktops get into the lift or up the stairs. Those decide the layout before cabinetry is chosen. A feasibility visit settles them, we agree a scope and specification, and a written quotation follows.
