A rear extension is one of the most straightforward and popular types of kitchen extensions. It involves extending the rear of a property into the available garden space, increasing the overall footprint of the home. By adding extra square footage, a rear extension creates valuable additional space that can be adapted to suit a wide range of needs.
Homeowners choose rear extensions for many reasons. A smaller rear extension can form a calm, light-filled retreat ideal for relaxing or hosting intimate gatherings. Larger designs often focus on creating open-plan kitchen and dining areas, providing the perfect setting for entertaining, family life, or accommodating a growing household.
The team at Delta Builders Ltd has extensive experience designing and building rear extensions in a wide range of styles, tailored to different property types. Our aim is to create an extension that blends seamlessly with the existing character of your home, while also introducing a striking new focal point that enhances open-plan living.
One of the key advantages of a single-storey rear extension is the strong connection it creates between indoor and outdoor spaces. By incorporating features such as bi-fold doors, we can open your kitchen directly onto the garden, creating a versatile living and entertaining area filled with natural light.
While practicality is essential to a successful extension, design plays an equally important role. A rear extension can introduce a contemporary edge to a period property or add warmth and comfort to modern homes. Whether clean and minimalist or bold and visually distinctive, every rear extension we deliver is designed to be both functional and aesthetically engaging.
The cost of a rear extension can vary depending on several factors, including whether your property is terraced, semi-detached, or detached, as well as the size of the extension and the chosen roof design. As a general guide, a 3m x 3m rear extension with a flat roof typically costs around £60,000.
At Delta Builders Ltd, we focus on providing clear and accurate cost guidance from the outset. All quotations are prepared with transparency in mind, and any potential additional costs are discussed early in the process to ensure you have a realistic understanding of the overall investment.
Our estimated costs usually include all core elements of the build, such as construction work, plumbing and electrical installations, glazing, external doors, and applicable VAT.
In addition to expert design and build services, Delta Builders Ltd offers full support with building regulations approval and planning matters. Our team can assist with planning applications and provide clear advice on permitted development rights, party wall agreements, and prior approval requirements.
We manage the process efficiently to ensure your rear extension complies fully with all relevant regulations, giving you complete peace of mind throughout the project. To learn more, you can explore our dedicated planning services for further guidance.
