Open-plan kitchen-diners in Finchley semis
The classic Finchley kitchen project removes the wall between the small original kitchen and the back reception room to create a bright open-plan kitchen-diner facing the garden. Because that wall usually carries the floor above, we install a steel beam sized by a structural engineer and signed off by Barnet Council building control. Many homeowners combine this with a rear extension to gain the extra depth these generous plots allow.
We fit bespoke or quality fitted units to suit the proportions of the room, then top them with quartz, granite or composite worktops chosen for durability and looks. Appliances are integrated cleanly, and we handle the plumbing, the tiling and the lighting ourselves, with the electrics certified by a registered electrician under Part P. Working in an interwar semi, we plan the run of units and the island around the new opening so the finished space flows as one.
Housing in Finchley
By the valuation list's count, Finchley holds about 19,250 homes, 41% houses and 59% flats; by age, 38% were built before 1919, 26% between the wars and 36% since 1945. Since most homes here are flats, a kitchen in a flat in Finchley drains to the building's shared soil stack, while a new extract through the outside wall needs the freeholder's licence first.
Kitchen extensions under a pitched roof in Finchley Garden Village
A new kitchen-diner in Finchley Garden Village may need a rear extension, and the village guidance shapes that room from the roof down. It asks for the height to be kept to a minimum and respectful of the window sills above, and says flat-roofed extensions will not be permitted. The pitched roof then sits low at the eaves, so the ceiling slopes and wall cupboards on the outside wall may not fit. Plan tall units against the original house wall, and route the extractor duct through the side wall or the roof slope before the rafters are set out, not after. Lighting goes on the rafters or the wall, since there is no flat ceiling void to hide it in.
59% of Finchley's homes are flats, and moving a kitchen within a flat in a converted house affects the rooms around it. Put a sink and dishwasher over a neighbour's bedroom and the lease is likely to require the freeholder's consent, a sound-deadening layer under the floor and a leak-proof waste route to the shared stack. The waste needs a steady fall all the way, which limits how far across the flat the sink can go. Ask for the freeholder's conditions in writing before the kitchen is designed, so acoustic floors and pipe routes are priced from the start.
Bespoke kitchens for N3 layouts
Finchley's older houses often have a kitchen with an awkward chimney breast, a larder recess or a door to a side passage, features that standard flat-pack kitchens ignore. We design around them, using made-to-measure cabinetry that fills the alcoves, squares off the room and makes the most of every wall. Considered task and ambient lighting lifts these rooms, which can otherwise feel dark at the back of the house.
On the larger interwar homes towards Mill Hill and Golders Green there is scope for a full kitchen-diner with an island, a run of tall units and a utility space. Whatever the layout, the notifiable electrical work is certified by a registered electrician under Part P, and we sequence the plumbing, tiling and worktop template so the kitchen goes in cleanly and works properly from day one.

FAQ
Frequently Asked Questions about Kitchen Renovation Finchley
Do you charge for a survey before quoting kitchen renovation in Finchley?
The survey for kitchen renovation in Finchley is free, and it is where the figure within £18,000 to £60,000 or more (indicative) is actually decided. At the N3 address GS Renovation checks what decides the job: consumer unit capacity decides whether an induction hob needs a new board. A written quotation follows; if you decide against it, nobody chases you. Ring 07472 424 226 whenever suits.
Does a new Finchley kitchen need the electrics upgrading?
Frequently yes, because modern appliances demand more than older installations were designed for. A Finchley kitchen with an electric oven, a hob, a dishwasher and small appliances needs dedicated circuits and adequate capacity at the consumer unit. Where the wiring dates from an earlier era it is replaced rather than extended. The work is notifiable and is certified when the kitchen is complete.
Can a sink go in an island in a Finchley kitchen?
Yes, provided the waste can reach the stack with enough fall. Putting a sink or a dishwasher in an island in your Finchley kitchen means running drainage under the floor to the existing soil connection, and that route needs a continuous gradient. In a solid floor it means cutting a channel. Establishing it before the layout is agreed avoids an island that has to be redesigned.
Where does the extraction go in a Finchley kitchen?
Outside, by the shortest sensible route. An extractor in your Finchley kitchen works properly when it is ducted through an external wall or the roof in a run with few bends. Recirculating filters remove some smells and no moisture, which matters in an open plan room. The duct route is decided with the layout, because it usually has to pass through a ceiling or a wall that is being finished.
What supports a stone worktop in a Finchley kitchen?
The units beneath it, levelled properly, and additional support wherever there is a span. A stone worktop in a Finchley kitchen is heavy and unforgiving, and it is templated only once the units are fixed and level. Spans over appliances, sink cutouts and overhangs on an island all need support designed in. Templating before the units are fitted is the most common cause of a worktop that does not fit.
How long is a Finchley kitchen out of use during a refit?
Several weeks rather than several days, and it is worth planning around. A Finchley kitchen refit runs from strip out through first fix plumbing and electrics, plastering, flooring, unit installation, worktop templating and fitting, then second fix and tiling. Worktop templating in particular cannot happen until the units are fixed and level, and the fabrication that follows adds time in the middle.
Can the kitchen in a Victorian Finchley back addition be widened into the side return?
Yes, by building across the narrow gap beside the back addition and removing its flank wall. 16% of Finchley homes are terraced houses, and in a Victorian terrace that side return is often the only unused ground. The new roof meets the neighbour's boundary, so a party wall notice from the building owner is likely, and the steel over the old flank wall is sized before the units are ordered.
What limits a kitchen refit in a newer Finchley flat?
The building's shared systems. 9% of Finchley homes were built in 2000 or later, and a flat of that age may have a whole-flat ventilation unit with an extract point in the kitchen, and sometimes sprinkler heads. Fitting a separate ducted hood or boxing over a valve can unbalance the ventilation. Ask the managing agent for the operation manual before design, and keep extract points and sprinkler heads where they are.
Can a kitchen extension in Finchley have a flat roof?
Outside Finchley Garden Village, often yes, subject to the usual permitted development or planning rules. Inside the village, the design guidance says flat-roofed extensions will not be permitted, so a kitchen extension there needs a pitched roof. Check whether the house is in the conservation area, designated in November 1978, before commissioning drawings, because a flat-roof design with a large roof lantern is exactly what would need redrawing.
