House Extensions in Slough

When your Slough home no longer provides the space your family needs, a house extension offers the perfect solution. Rather than facing the expense and upheaval of moving, an extension adds valuable room while keeping you in the location you love. With Slough’s excellent transport links via the Elizabeth Line and proximity to Heathrow, it is easy to see why so many homeowners choose to extend rather than relocate.

We design and build house extensions across Slough, from single storey rear extensions creating spacious kitchen-diners to double storey additions providing extra bedrooms and bathrooms. Whether you need a bright open-plan living space, a dedicated home office, or simply more room for a growing family, we deliver extensions tailored to your requirements and budget.

Our service covers every aspect of your extension project, from initial design and planning applications through to construction and finishing. We coordinate all trades, manage Building Regulations compliance, and keep you informed throughout. You deal with one team from start to finish, ensuring your project runs smoothly and delivers the results you expect.

Our Extension Services

Home Extension 

Single Storey Extensions

Single storey rear extensions are our most popular choice for Slough homeowners wanting additional ground floor space. They create room for spacious kitchen-diners, larger living areas, or dedicated home offices without the cost of building upward. Under permitted development, you can typically extend 3 metres from the original rear wall for attached houses or 4 metres for detached properties without planning permission. Larger extensions up to 6 or 8 metres are possible through the prior approval process. We design single storey extensions that maximise natural light through bi-fold doors and skylights, creating bright, welcoming spaces that transform how your home works.

Double Storey Extensions

When you need both additional ground floor and first floor space, a double storey extension delivers excellent value. Building two storeys costs significantly less than constructing the same space as separate single storey projects because foundations, walls, and roof are shared. Double storey extensions suit growing families needing a larger kitchen-diner below with extra bedrooms or bathrooms above. These extensions typically require planning permission and must consider impact on neighbours and light to adjacent properties. We design double storey extensions that complement your existing home, ensuring the addition looks like it has always been part of the property.

Side Return Extensions

Many Victorian and Edwardian terraces and semi-detached houses in Slough have narrow side returns running alongside the property. Extending into this unused strip adds valuable width to your kitchen without taking significant garden space. Side return extensions are particularly effective when combined with a modest rear extension, transforming a narrow galley kitchen into a generous open-plan living space. The side return approach suits properties in areas like Central Slough and Chalvey where period homes often feature this wasted passage. We design side return extensions that maximise the space gained while maintaining natural light to existing rooms.

Wrap-Around Extensions

Wrap-around extensions combine rear and side extensions into one L-shaped structure, maximising the space gained from your project. This approach suits corner plots or properties where both side and rear extension are feasible. Wrap-around designs create the largest ground floor transformations, often doubling the size of your kitchen and living space. They require careful design to maintain natural light to existing rooms and ensure the extension complements your home’s proportions. We plan wrap-around extensions to work with your property’s specific characteristics, delivering dramatic transformations that enhance both your living space and your Slough property’s value.
