Transform your space with a kitchen extension
A kitchen extension is one of the most valuable home improvements you can make. Whether you're creating an open-plan living space, adding a dining area, or simply gaining more room for cooking and storage, we work with trusted local builders to design and coordinate kitchen extensions that transform how you live.
Why extend your kitchen?
More Space
Gain valuable square footage for cooking, dining, and entertaining without moving house.
Open Plan Living
Create seamless connections between kitchen, dining, and living areas for modern family life.
Increased Property Value
Kitchen extensions typically add significant value to your home, often more than the cost of the extension.
Better Natural Light
Large windows, bi-fold doors, and rooflights flood your extended kitchen with natural light.
Improved Workflow
Design a kitchen layout that works perfectly for your lifestyle with ample prep space and storage.
Future-Proof Your Home
Create a space that adapts to changing family needs and modern living requirements.
Types of kitchen extensions
Single-Storey Rear Extension
The most common type of kitchen extension, extending backwards into your garden. Perfect for creating open-plan kitchen-dining spaces with bi-fold doors opening to the garden.
Side Return Extension
Utilise the side return of your property (the space between your house and boundary) to widen your kitchen. Often combined with rear extensions for maximum space.
Wraparound Extension
Combine rear and side extensions to create a wraparound extension, maximising space and creating a truly open-plan living area.
Double-Storey Extension
Extend both ground and first floor to create a larger kitchen below and additional living space or bedrooms above. Requires planning permission.
Planning permission and building regulations
Permitted Development Rights
Many single-storey rear extensions fall under permitted development, meaning you may not need planning permission if:
- The extension doesn't extend more than 6m from the original house (8m for detached)
- It's no higher than 4m
- It doesn't cover more than 50% of your garden
- It meets other specific criteria
When You Need Planning Permission
You'll need planning permission for larger extensions, double-storey extensions, or if your property is in a conservation area or listed. We work with local architects and can guide you through the planning process, helping with applications and liaising with your local council.
Building Regulations
All extensions require building regulations approval, regardless of planning permission. This covers structural safety, insulation, fire safety, and electrical work. We coordinate with builders to ensure all work meets current building regulations.
Designing your kitchen extension
Initial Consultation
We assess your existing space, discuss your vision, and explore extension possibilities. We'll consider your budget, planning constraints, and how you want to use the new space.
3D Visualisations
See your extended kitchen before any building work begins. Our detailed 3D visualisations show exactly how your new space will look and function.
Builder Coordination
We work with trusted local builders to coordinate the extension build and kitchen installation, ensuring seamless project management from start to finish.
Kitchen Installation
Once the extension is complete, we install your bespoke kitchen, ensuring perfect integration with the new space and existing areas of your home.
Kitchen extension costs
Extension costs vary significantly based on size, complexity, and location. As a rough guide:
- Small single-storey extension (15-20m²): £25,000 - £40,000
- Medium extension (25-35m²): £40,000 - £60,000
- Large extension (40m²+): £60,000 - £100,000+
These costs typically include building work, but not the kitchen itself. Kitchen costs are separate and depend on your chosen range and specifications. See our kitchen prices guide for more information.

“We are absolutely delighted with the kitchen the design for which we developed with Matt’s great patience over a long period of time. The result has given us the perfect layout for our needs. Matt took great care to inform us of progress and the process of installation.”
