A Maida Vale kitchen may move down to a villa's lower ground floor, across a mansion flat or through a wall between rooms, and the structure decides how far it can go.
Plenty of houses here stand on a lower floor: Westminster's 1966 schedule describes Warrington Crescent's mid-Victorian houses as four storeys with an attic above and a basement below.
Units, steelwork and services are worked out together on one drawing set, and no cabinet is ordered until the three agree with each other.

A kitchen on the lower ground floor
The 1850s pairs on the southern half of Clifton Villas, for instance, have three storeys above a basement.
In a listed house, where the rooms sit, how they rank and the old floor levels may all be protected, which makes a move downstairs a listed building matter as well.
If the floor is suspended timber, insulation fitted underneath should go no deeper than the joists and must leave the air bricks clear.
A kitchen below street level needs daylight and a dry floor, so the lightwell, the damp-proofing and the invert of the drain are checked before any unit is placed.

Opening rooms into each other
Cutting or widening an opening in an outside wall means carrying the masonry above on new beams, usually two, and fire-protecting any steel.
An internal chimney breast can come out without planning permission, yet as part of the structure it always needs building regulations approval.
Inside a flat, a knock-through in a wall owned by the landlord needs the landlord's permission.
Steel sizes, padstones and propping are fixed by our engineer before we quote, so the structural work is priced once and not revisited.

Extraction, ducts and windows
Every new kitchen needs a means of extract to cut condensation and clear cooking smells.
For purge ventilation the opening window should equal a tenth of the floor area if it opens between 15 and 30 degrees, or a twentieth if it opens further.
Ducts, flues and plant on the outside of the building should be designed, placed and screened with care, Westminster's City Plan asks.
When a duct cannot reach outside, we fit a recirculating hood whose filters can be changed without taking the wall units down.

Kitchens in mansion flats
Moving a radiator or swapping carpet for timber counts as an alteration a lease can control, and gas pipework is safety-critical, LEASE explains.
Where the landlord owns the shared floors or a structural wall, underfloor heating through them or a knock-through needs the landlord's agreement.
The lease may also restrict touching the boiler system or drilling the external wall for a flue.
Relocating a sink in a flat means finding a new fall for the waste, so a floorboard comes up and the void is measured before the plan is signed off.

Layouts for villas, terraces and flats
Where a villa's old kitchen and scullery sit side by side at the back of the lower floor, joining the two usually gives room for a table without touching the front rooms.
Where a dining room and kitchen are joined on the ground floor, we keep a nib of wall and a downstand at the old line, so the two rooms still read as a pair.
If a mansion-flat kitchen is a narrow galley off the hall, tall storage at one end, a slim dishwasher and an induction hob make the most of it without moving services.
Heating under the new floor
Heat pumps run better over underfloor heating, though an outdoor unit in a conservation area may need planning permission.
If the floor is coming up anyway, heating pipes and insulation go in during the same visit and are pressure tested before the screed is poured.

Deliveries and the order of work
Westminster takes applications to suspend a parking bay for a skip delivery or for building works.
A Westminster skip licence lasts one month, and each suspended bay takes only one skip.
We take out the old kitchen, then fix structure, pipes and cables, then plaster and floor, and fit the units last; worktops are measured from the fitted carcasses. Cabinets, a dresser or a larder can be made to measure by our Maida Vale joinery team.

Questions about kitchen renovation in Maida Vale
Could the kitchen move to the lower ground floor of a listed house?
It may, but the order of rooms and historic floor levels can be protected, so listed building consent needs thinking about from day one.
Will taking out a chimney breast need permission?
Building regulations approval, every time; planning permission, not for an internal breast.
Is an extractor compulsory?
A new kitchen must have some means of extract ventilation for condensation and smells.
Can I replace the boiler in my flat?
Check the lease, which may restrict changes to the boiler system or new flues through the outside wall.
Where should the extract duct come out?
Westminster wants external ducts and flues carefully placed and screened, so the rear of the building is our first choice.
How is dust kept out of the rest of the house?
The kitchen is closed off behind sealed screens with a zip door, saws run with extraction, and the route out is cleaned at the end of every day.
