Kitchens Replanned for South West London Living
A kitchen renovation in South West London is rarely just a kitchen. It usually involves layout surgery, hidden structural work, services relocation and a careful balance between period character and the way people cook, gather and work today.
The region's Victorian and Edwardian terraces, mansion flats, townhouses, villas and family houses with deep gardens come with tight service zones, chimney breasts, awkward floor levels and conservation-sensitive details. We resolve those constraints with designers and builders working as one team instead of handing the hard parts off to a separate design studio.
From Chelsea, Fulham, Kensington, and Wimbledon to the wider South West London market, our kitchen projects combine bespoke cabinetry, appliance planning, lighting, flooring and any enabling works required to create a coherent open-plan result.
South West London spans several planning authorities. Kensington and Chelsea protects nearly three quarters of the borough with 38 conservation areas, Hammersmith & Fulham has 44 covering about half of its area, and Wandsworth applies Article 4 controls in its conservation areas. Richmond publishes a statement for each of the four conservation areas covering its town and riverside, and Merton publishes a map for each of its seven Wimbledon conservation areas.
In a terraced house or a converted flat, the work turns on narrow rooms, shared walls and the route the extract takes out of the building. We survey, design and build the kitchen under one appointment, with our own architects and structural engineers drawing the details the councils and freeholders ask for.

Kitchens in the Back Addition of a Terrace
Hammersmith & Fulham's planning guidance describes much of its housing as late Victorian and Edwardian terraces: a narrow front of two or three floors, sometimes over a semi-basement, with a narrower, usually lower back addition behind.
The gaps between neighbouring back additions are tight. The same guidance says rooms facing into them can already be at the margin of acceptability, and further extension of back additions, especially above ground floor, will generally be resisted.
Inside the existing walls, we test whether the back-addition kitchen can borrow space from the room in front, where a beam would sit if a wall comes out, and how a single run plus a narrow island fits the width. Widening into the side return is an extension; our kitchen extensions page covers it.

Flues, Pipes and Chimneys in Hammersmith & Fulham
Hammersmith & Fulham's planning FAQ says fitting a flue, pipe or chimney to a flat or maisonette requires planning permission. For a house in a conservation area, or one an Article 4 direction reaches, a proposal touching the front or side elevation is likely to need permission too.
Where the house is listed, the council expects listed building consent to be needed in most cases, even for work permitted development would otherwise allow.
In a house that stays occupied, stripping out a kitchen is internal demolition, which the council's Section 80 guidance exempts from a demolition notice; other demolition may need a notice to the council, copied to the occupiers next door.
Our usual extract route leaves through the rear wall of the back addition, where it is out of public view and the duct run to the hob stays short.

Article 4 Streets, Vents and Plant in Kensington and Chelsea
Kensington and Chelsea uses Article 4 directions to remove permitted development for minor outside changes, such as new windows or front doors, at named properties on streets that include Kensington Square, Carlyle Square, Ladbroke Grove and Earls Court Square.
For an unlisted house in a conservation area, its Local Plan allows double glazing without planning permission where similar materials are used, unless an Article 4 direction applies. A mansion block, typically held in many ownerships, has no permitted development rights.
In the Pembridge appraisal, vents, flues, plumbing and wiring fixed to outside walls count as clutter unless placed with sympathy, and plant left exposed on a roof is said to break its line.
On these streets we match any replacement window or door to the original pattern and run kitchen pipework inside the building wherever the structure allows.

Kitchen Extraction Under Approved Document F
Approved Document F covers ventilation in a refitted kitchen. When building work is done in a kitchen in an existing home, it says existing fans, including cooker hoods that extract outside, should be kept or replaced, with checks that retained devices work.
A room that had no ventilation system before the refit need not be given one, though more may be required where the work would make the building less compliant than it was.
A replacement extractor fan or cooker hood that runs on the cabling already there needs no notice to a building control body.
For intermittent extract, the document's table gives 30 litres per second for a kitchen whose cooker hood vents outside and 60 where it does not, and it says a hood that only recirculates air does not meet Part F by itself.
We size the duct, the wall terminal and the make-up air together, so an island hood does not starve the room or pull fumes from an open-flued boiler.

Removing a Kitchen Chimney Breast
Richmond's building control guidance warns that taking out a ground floor breast without beams to carry the stack and breast above can leave an off-centre load that could eventually pull the wall over.
It says the work must comply with the Building Regulations 2010 and needs a submission, and that a chimney forming part of a party wall brings duties under the Party Wall etc Act 1996.
Once the breast is gone, a recess for the flues sometimes appears in the wall; Richmond says it should be filled with brickwork to the wall's thickness and density, for sound insulation.
Our engineer specifies the beams or brackets, the trimmed floor where the hearth was, and the infill, so the kitchen wall is flat and true before cabinets are scribed to it.

Flats in Converted Houses and Estate Blocks
GOV.UK notes that most flats are leasehold, and that the lease says whether permission is needed for alterations.
LEASE lists drilling through an external wall for a flue and changing the boiler system among the works other lease clauses can restrict, even where alterations are allowed.
On the Cadogan estate the lease sets the limits on alterations, and where Cadogan's consent is required it is given through a Licence to Alter.
Wandsworth's householder guidance sends the owner of a flat in a converted house to the full planning application rather than the householder form.
Where the plan allows, sinks and dishwashers stay over the flat below's kitchen or bathroom, and new waste runs fall within the flat's own floor rather than through a neighbour's ceiling.

Working Hours and Deliveries Across South West Councils
Kensington and Chelsea lets work that can be heard past the site boundary run between 8am and 6pm, Monday to Friday; on Saturdays, Sundays and bank holidays it needs the council's written permission first.
Its Code confines deliveries and collections to 9.30am to 4.30pm on weekdays, requires a licence for any skip on the highway, and classes internal refurbishment as Category 3.
Hammersmith & Fulham tries to hold noisy building work to weekday hours of 8am to 6pm and Saturday hours of 8am to 1pm, and to stop it altogether on Sundays and bank holidays.
We programme the cutting, coring and strip-out for weekdays in every borough, so one plan works whether the house is in Kensington and Chelsea or across the boundary in Fulham.

Questions about kitchen renovation in South West London
Does a new cooker hood need building control approval?
Approved Document F says a like-for-like hood or fan on the existing cabling needs no notification. Where the duct takes a new route through an outside wall, check the planning and lease position first.
Can I fit a recirculating hood instead of ducting outside?
On its own, no: Approved Document F says a recirculating hood does not give Part F ventilation. It can work alongside a separate extract fan sized to the 60 litres per second rate.
Is planning permission needed for a kitchen flue in Fulham?
In a flat or maisonette, yes, according to Hammersmith & Fulham. For a house in a conservation area or under an Article 4 direction, a flue on the front or side is likely to need permission.
Is it safe to remove a kitchen chimney breast?
It can be, with the right support. Richmond warns that removing a ground floor breast without beams risks an eccentric load that could pull the wall over, and it requires a Building Regulations submission.
Can I double glaze the kitchen windows in a Kensington conservation area?
For an unlisted house, yes in principle: RBKC's Local Plan allows it with similar materials and no planning application, unless the street is under an Article 4 direction.
When can deliveries arrive in Kensington and Chelsea?
RBKC's Code allows deliveries and collections from 9.30am to 4.30pm on weekdays, ending at 3pm instead when the route passes a school or another traffic-sensitive use.
