Open-plan kitchen-diners in Lewisham terraces
In a Lewisham terraced house, a common kitchen project opens the rear closet wing through to the middle reception, creating one bright kitchen-diner across the back of the house. That dividing wall is normally load-bearing, so the knock-through needs a steel beam, sized by a structural engineer and signed off by Lewisham Council building control. Fill in the side return at the same time and the room widens dramatically, ideal for the deep plans of these terraces.
We design the new kitchen around how you actually cook and gather, planning the layout, sockets, lighting and ventilation before a single unit goes in. Quartz, granite and composite worktops all suit these spaces, paired with integrated appliances for a clean finish. Underfloor heating, a large rooflight over the old side return and considered task lighting make the room work all year. Plumbing, electrics, tiling and decoration are all handled by our own team.
Housing in Lewisham
By the valuation list's count, Lewisham holds about 133,910 homes, 40% houses and 60% flats; by age, 34% were built before 1919, 18% between the wars and 45% since 1945. Since most homes here are flats, a kitchen in a flat in Lewisham drains to the building's shared soil stack, while a new extract through the outside wall needs the freeholder's licence first.
When a Lewisham kitchen refit becomes building control work
Lewisham's building control fees chart has a line of its own for installation of a new kitchen, with 3 inspections. A straight swap of units in the same positions is not normally building control work. A refit that moves the sink to an island with new drainage, opens a wall to the dining room or adds a new extract is no longer a straight swap. Once any of that is in the plan for a Lewisham kitchen, the job goes in with a notice, and the chart's kitchen line assumes three inspection visits that need space in the programme. Ideally they fall before the worktops are templated and before any wall or floor is closed up.
Lewisham's housing is 60% flats, and in a flat above another home every waste and supply joint sits over someone else's ceiling. Moving a sink across a flat lengthens the waste run under the floor, and the fall it needs may be hard to find where the joists run the wrong way in a converted house. We plan the route with the boards up, pressure test the new pipework before the floor goes back, and tell the owner below which day the water will be off. In a Lewisham conversion that single day of notice saves a lot of goodwill.
Bespoke fitted kitchens for Lewisham homes
Period Lewisham houses come with alcoves, chimney breasts and tall ceilings that rarely suit off-the-shelf units. Made-to-measure cabinetry uses every awkward corner, whether that is a run of tall larders beside a retained chimney breast or a bank of drawers under the window looking onto the garden. From handleless contemporary designs to classic in-frame Shaker kitchens, we build to match the age and proportions of the house.
Not every Lewisham kitchen needs a wall removed. In a smaller terrace in SE4 or SE14, or a flat near New Cross, we often gain far more from a cleverer layout, better storage and the right worktop and lighting than from major structural change. None of this needs planning permission, though any new circuit or consumer unit change is notifiable under Part P, so it is certified by a registered electrician or notified to building control. You get a kitchen that fits the room and the way you live.
Doing the structure now, the kitchen later
Not every Lewisham household wants to do the whole thing at once, and there is a sensible way to split it. The structural work, the beam, the opening, the first-fix plumbing and electrics and the plastering, is the disruptive and dusty part and is best done in one go. The kitchen itself can follow months later without any of that having to be revisited, provided the first fix was set out for the final layout.
That proviso is the whole point. Waste positions, the hob and extractor position, the island supplies buried in the floor and the circuits back to the consumer unit all have to be decided before the plaster goes on, even if the units are years away. We draw the finished kitchen at the start, install to that drawing, and photograph every service run before it is covered so nothing has to be chased out of finished plaster a year later.

FAQ
Frequently Asked Questions about Kitchen Renovation Lewisham
What happens to the kitchen renovation price if the scope changes in Lewisham?
The kitchen renovation price in Lewisham moves visibly when the scope changes, because the quotation is itemised within £18,000 to £60,000 or more (indicative). A change at SE13 is priced against the same lines rather than renegotiated, and any change touching the approvals, such as Part F extraction and Part P certification for the circuits, is flagged. GS Renovation issues a written variation and waits for approval.
Do I need consent to build over the drain in my Lewisham kitchen extension?
Where the sewer is shared or public, yes, through a build over agreement with the water company. Across SE6, SE13 and SE23 many terraces have a shared run crossing the rear garden exactly where an extension wants to sit. We survey and record the line, help you apply for the agreement, and build the foundations and any access chamber to the engineer's design and what the water company will accept.
How long does a Lewisham kitchen renovation take?
On site, about 3 to 5 weeks for a straight replacement, or 6 to 8 weeks where a wall is taken out with steel. The order is fixed: strip out, first fix services, plaster, fit carcasses, template the worktops, then fit sinks, hobs and appliances once the worktops arrive.
Can I fit enough units in a narrow Lewisham terrace kitchen?
It takes planning. Narrow kitchens in terraced houses lose wall to the back door, windows and a radiator, which leaves little unbroken run for units. Tall units at one end, a galley layout, or moving the radiator to a plinth heater gain storage. Where more is needed, joining the kitchen to the next room with steel is the structural answer.
Can the hob go on an inside wall in my Lewisham kitchen?
Yes, if the extract can reach outside. Part F requires kitchen extraction to be ducted to outside, so a hob on an internal wall needs a duct run across the ceiling. Joist direction decides whether that duct can run between joists or needs boxing below. Plan the route before the units and ceiling are fixed.
Will my Lewisham kitchen floor take stone or porcelain tiles?
It depends on the floor below. Victorian suspended timber floors flex, and rigid tiles crack or come loose unless the floor is stiffened and overboarded first. A solid floor may need a damp check before tiling. Choose the tile with the floor structure in mind, because the preparation is part of the first fix.
Does a Lewisham kitchen extension over the back drain need anything before work starts?
Yes. Lewisham's building control guidance says you must apply for a build over agreement before doing any works if your home is within 3 metres of a public drain or 1 metre of a public lateral drain. Behind a Lewisham house the kitchen is often where the drains leave the building, so a kitchen extension is where this tends to arise. Apply early to the water company, since the agreement is separate from building control approval and the dig cannot begin until it is settled.
Can a new cooker hood vent go through the wall of a Lewisham conservation area flat?
Only with planning permission if it shows outside. Lewisham says flats or subdivided houses in conservation areas lack permitted development rights, so any change to the exterior needs an application. A new vent grille, a moved boiler flue or a new window for a relocated kitchen all count. Rear walls count too. In a Lewisham flat we look first for an existing opening or duct the extract can use, or fit a recirculating hood, so the kitchen is not held up.
Will Lewisham building control want to see the drains when a kitchen moves?
It can. Drains inspection and testing is one of the typical inspection stages Lewisham Building Control lists. When a kitchen moves to the back of a Lewisham house or into an extension, the new waste runs to the existing chamber, and the inspector can ask to see that run tested before it is covered. We leave the joint to the chamber exposed and test the line, so the screed or floor goes down only after it has passed.
