If you are searching for kitchen extension builders near me, we deliver practical design ideas, clear guidance on costs, and a professional build that adds real value to your home.


Kitchen House Extension Ideas for London Homes

London properties come in all shapes, from Victorian terraces to 1930s semis and modern homes, so the best kitchen house extension is the one that suits your layout and planning constraints. Popular options include rear kitchen extensions to create a generous open-plan kitchen-diner, side return kitchen extensions to widen a narrow ground floor, and wrap-around configurations for maximum footprint. We help you choose glazing, rooflights, door styles, and internal layouts that improve natural light and flow, while keeping the design in keeping with your home. The goal is simple: create a space that looks right, feels bright, and works better for everyday life.


Kitchen Extension Cost London and What Affects the Price

The cost of a kitchen extension in London depends on the size, structure, access, specification, and the level of finish you choose. Groundworks, steelwork, drainage changes, and structural openings can influence the budget, as can premium items like large sliding doors, roof lanterns, underfloor heating, and bespoke kitchens. We keep pricing clear by explaining what is included, what is optional, and where you can spend for impact without wasting money. If you want a realistic budget range, we can assess your property, discuss your priorities, and guide you towards a build specification that matches your goals.


Planning Permission and Building Regulations for Kitchen Extensions

Many kitchen extensions London projects can fall under permitted development, but it depends on your property, location, and the size and design of the extension. Conservation areas, flats, and certain layouts may require full planning permission. Even when planning is not required, building regulations still apply, covering structural safety, insulation, ventilation, drainage, electrics, and fire safety. We help you understand what you need from the start, coordinate drawings and submissions where required, and ensure the build is completed to the correct standards. This protects your investment and makes the process far less stressful.


Design and Build Kitchen Extensions London From Consultation to Completion

A successful design and build kitchen extension starts with listening. We begin with a consultation to understand your space, your ideas, and what you want the extension to achieve. Next, we develop a practical plan that considers layout, light, structure, and finishes, then we schedule the build with clear stages and realistic timelines. During construction, we manage trades, materials, inspections, and quality control, keeping the site tidy and communication clear. The result is a finished extension that feels like it has always belonged to your home, adding comfort, function, and long-term value.

Frequently Asked Questions

For a single storey rear kitchen extension, permitted development allows up to three metres projection for terraced and semi-detached homes, and four metres for detached properties. The neighbour consultation scheme can extend this to six or eight metres respectively. Height limits and eaves restrictions also apply. We assess your property and confirm exactly what is achievable before any drawings are prepared.

Yes. A kitchen extension is one of the highest-return home improvements in London. An open-plan kitchen-diner that connects to the garden is consistently one of the most desirable features for buyers. The added square footage, improved layout, and increased natural light all contribute to a stronger sale price. The key is a well-designed, well-built result that feels like a natural part of the original home.

Bifold and sliding doors are the most popular choice for the rear elevation, opening the kitchen fully to the garden. Rooflights and roof lanterns are highly effective for bringing daylight deep into the space, particularly in side return extensions where the roof is the primary light source. We advise on the right combination for your layout, orientation, and budget to get the best possible light throughout the day.
