Kitchen Extensions North London
Design-and-build kitchen extensions for North London homes, planned around more space, more natural light, a stronger garden connection and a finished kitchen that works beautifully every day.
Design & Build Kitchen Extensions for North London Homes
We help homeowners create brighter kitchen diners, open-plan family spaces and premium kitchen finishes with one clear route from first survey to completed build.
Rear kitchen extensions
A rear kitchen extension can open the back of your home into a larger kitchen, dining and living space with rooflights, slim-frame glazing and better garden views.
Side return kitchen extensions
Ideal for narrow Victorian and Edwardian terraces in areas such as Crouch End, Highgate, Islington and Muswell Hill, a side return can turn wasted side space into valuable kitchen width.
Wraparound kitchen extensions
A wraparound extension combines rear and side space to create a larger open-plan kitchen diner, often with a kitchen island, dining zone and full-height glazing.
Open-plan kitchen diner layouts
We plan the structure, glazing, lighting, ventilation, heating and kitchen fit-out together, so the finished room feels practical, bright and properly connected to the garden.
Why North London Homeowners Choose House Extensions London
Your kitchen extension needs more than building work. It needs planning awareness, structural detail, careful project management and a finish that suits how your family uses the space.
We help with planning permission, permitted development checks, Building Regulations, structural calculations, party wall matters and Building Control.
From RSJs, foundations and drainage to rooflights, sliding doors, kitchen fit-out and premium worktops, we plan the full route.
Your build is coordinated through survey, drawings, approvals, specification, construction, snagging and handover.
Quartz, granite, marble, Dekton and porcelain worktops can be planned from the start, avoiding awkward late-stage layout changes.
Send photos, drawings or your postcode and we will advise on likely options, budget drivers and next steps before you commit.

Planning a Kitchen Extension in North London
North London kitchen extensions need postcode-specific checks. Some rear and side return projects may fall under permitted development, but larger rear extensions, wraparound layouts, conservation areas and flats often need a different planning route.
Useful official guidance: Planning Portal extension guidance, GOV.UK permitted development guidance, GOV.UK party wall guidance, LABC homeowner guidance.
- Barnet and Enfield: family houses often have more rear garden depth, but previous extensions, drainage and boundary positions still need checking.
- Haringey and Camden: conservation areas, narrow streets and period homes can make design, materials and neighbour impact more sensitive.
- Islington and Highbury: terraces and shared boundaries often need careful party wall planning, structural design and access coordination.
- Building Control: structure, fire safety, insulation, ventilation, drainage and electrics must comply before completion.

Kitchen Extensions North London FAQs
Do I need planning permission for a kitchen extension in North London?
Some kitchen extensions can be built under permitted development, but many projects need planning permission, especially wraparound extensions, conservation-area homes, flats and larger proposals. We check the route before design work progresses.
Are side return and rear extensions permitted development?
Some single-storey rear and side extensions may qualify if they meet strict limits. The rules depend on height, depth, width, boundaries, previous extensions and property type.
How much does a kitchen extension cost in North London?
Many projects fall between £70,000 and £220,000+ depending on size, structure, glazing, drainage, kitchen specification, worktops and finishes. A survey and drawings are needed for accurate pricing.
How long does a kitchen extension take from design to completion?
The full route can take several months including design, permissions, structural calculations, party wall matters and construction. Site duration depends on size, access and specification.
Can I stay in my house during the build?
Often yes, but it depends on the level of disruption, kitchen downtime, services, dust control and whether temporary cooking arrangements are practical.
What type of kitchen extension works best for a Victorian terrace?
A side return or rear-and-side layout often works well because it adds width to the existing narrow kitchen and can bring daylight through rooflights or a roof lantern.
Do you handle structural calculations, party wall matters and Building Regulations?
We can help coordinate structural calculations, Building Regulations information, Building Control and party wall requirements as part of the design and build route.
