A well-planned extension is one of the best ways to increase the size and usability of your home without the cost and hassle of moving. At Guildford Builders, we design and build high-quality extensions tailored to your lifestyle, your property and your long-term plans.
Whether you want a larger kitchen, an extra bedroom, an open-plan living area or improved flow throughout your home, our skilled team delivers extensions built to last — with clear communication and careful project management every step of the way.
Create More Space With a High-Quality Home Extension
Single storey rear extensions remain the most popular way to add space to Guildford homes. By extending into your garden, you can create the open-plan kitchen-diner modern families desire, add a spacious utility room, or build a garden-facing living area flooded with natural light. Large bi-fold or sliding doors blur the boundary between indoor and outdoor living, perfect for entertaining and family life. Many single storey extensions fall within permitted development, avoiding planning application delays. We design rear extensions that complement your property’s character while delivering the practical space your household needs.

Many Guildford properties, particularly Victorian and Edwardian terraces, feature narrow side passages that serve little practical purpose. A side return extension reclaims this wasted space, typically widening kitchens by 1.5 to 2.5 metres and creating room for dining areas, utility spaces, or improved layouts. Combined with a rear extension, side returns create impressively spacious open-plan living areas. Roof lanterns or skylights bring natural light deep into the extended space. These extensions often fall within permitted development rights, making them a straightforward route to significantly improved ground floor accommodation without complex planning processes.
Wrap-around extensions combine side return and rear extensions into a single L-shaped addition, maximising the space gained from your project. This approach works particularly well for corner plots and properties with generous side access, creating substantial new accommodation in one comprehensive build. Wrap-around designs suit open-plan kitchen-dining-living spaces where the extended footprint accommodates distinct zones for cooking, eating, and relaxing. Large format glazing on multiple aspects creates bright, airy interiors with garden views from throughout the space. We design wrap-around extensions that balance ambition with practicality, delivering transformative results within realistic budgets.
