Bespoke house extensions across the West Midlands
Cubit Contracts creates beautifully crafted house and kitchen extensions for homeowners across the West Midlands. Our team combines decades of experience with a third generation family building heritage to deliver high quality spaces designed for modern living.


Transform your home with a beautifully designed extension
A thoughtfully designed house extension can transform how your home looks, feels and functions. Many homeowners reach a point where their property no longer suits the way they live, whether that means a kitchen that feels too small, a layout that feels disconnected, or simply a lack of space for family life and entertaining.
At Cubit Contracts, we specialise in elegant, high quality house and kitchen extensions that enhance both your home and lifestyle. From spacious rear extensions to light filled kitchen extensions and open plan living areas, every project is built with careful attention to detail and craftsmanship for homeowners across the West Midlands.
Homeowners can also explore our dedicated services for house extensions in Bromsgrove, house extensions in Knowle, house extensions in Dorridge, house extensions in Lapworth and house extensions in Redditch.
Plan an extension around the way you live
The best extensions start with how you want to use the space. Deciding early where the kitchen, dining and living areas will sit, how the new room connects to the existing house and where the light will come from helps create a layout that feels natural from the day you move in.
Rooflights, vaulted ceilings and wide glazed doors can bring daylight deep into an open plan room and connect it to the garden. These details are easiest to get right when they are planned alongside the structure, insulation and heating rather than added later.
Many single storey rear extensions can be built under permitted development, but limits on size, height and materials apply, and some homes need full planning permission. Building Regulations approval is needed either way. The Planning Portal’s extension guidance is a useful starting point, and our guide to planning permission for house extensions in the West Midlands explains the main rules in more detail.

Common questions about house extensions
What types of house extensions do you build?
Cubit Contracts delivers a wide range of house extensions including rear extensions, side extensions, wraparound extensions and larger structural transformations. Many of our projects focus on creating open plan spaces where kitchens, dining areas and living rooms connect seamlessly.
Our team specialises in extensions that integrate naturally with the existing property so the finished space feels like a genuine part of the home rather than a later addition.
If you are weighing up your options, our comparisons of rear and side return extensions and single and double storey extensions are a useful place to start.
Do you build kitchen extensions?
Yes. Kitchen extensions are one of the most popular projects we undertake.
Many homeowners want to create a spacious kitchen and dining area that becomes the heart of the home. This often includes large sliding doors, rooflights or lanterns to maximise natural light and strengthen the connection between the house and garden.
Cubit Contracts has extensive experience delivering high quality kitchen extensions designed for modern family living and entertaining.
For inspiration, see our design ideas for open plan kitchen extensions.
How much does a house extension cost?
The cost of a house extension varies depending on factors such as size, specification, glazing, structural work and ground conditions.
Some homeowners approach us after receiving architectural drawings that do not align with realistic budgets. Our experience allows us to review designs early and provide guidance so projects remain achievable while still delivering the results homeowners want.
Our guide to house extension costs in the West Midlands explains what affects the price in more detail.
How long does it take to build a house extension?
Construction time depends on the size and complexity of the extension. Smaller projects may take several months, while larger structural extensions or projects involving internal alterations may take longer.
At Cubit Contracts we carefully plan each project and communicate timelines clearly so clients understand how their build will progress.
Do you work with architects?
Yes. Many of our projects begin with architect prepared drawings. We regularly collaborate with architects and designers and can provide construction insight during the planning stage to help ensure designs remain practical and aligned with the project budget.
