The Lasting Value of Extending Your Home
Investing in a home extension is one of the most refined ways to elevate both the comfort and functionality of your living environment. It allows you to reimagine your layout, introduce expansive light-filled spaces, and tailor every corner to your lifestyle without the disruption or expense of relocating.
Whether you envision a statement kitchen, an elegant open-plan living area, or a private workspace, an extension creates room for true design flexibility and long-term value. A thoughtfully crafted single-storey extension enhances flow, maximises underused areas, and increases market appeal. Over time, homeowners opting for single-storey rear extensions experience a remarkable upgrade in both convenience and everyday living quality.
Types of Single-Storey Extensions
- Single Storey Kitchen Extension – Creates a refined, light-filled space designed for cooking, dining, and socialising, often becoming the architectural centrepiece of the home
- Single Storey Rear Extension – Extends your property into the garden for seamless indoor–outdoor living, making it ideal for modern layouts and considered one of the most versatile single-storey rear extensions.
- Single Storey Side Extension – Perfect for widening narrow layouts, adding valuable floor area while elevating overall flow and functionality in single-storey side extensions.
- Single Storey Wrap Around Extension – Combines rear and side elements for a luxurious, full-footprint transformation, offering exceptional space efficiency and substantial value relative to single storey extension pricing.

Here’s what our clients have to say.
This was my first project and I was nervous at the beginning as every thing was new to us. Nadir was very helpful in guiding us through the entire project from planning stages to choosing materials to assigning builders; giving us assurances that the project would be finished on time and on budget. He also provided us with ideas for interior design. The build was of high quality with great care taken throughout. Geroge and his team were excellent builders and really gave us a peace of mind. There were issues with some of the materials (not their faults but due to Covid restrictions and the subcontractors), all of which were sorted out by Nadir and George between themselves. I’m hugely impressed by the after build care (nagging jobs and other issues). They were all addressed without fuzz.
A true test of a beautiful house is whether you are proud of showing it to guests. I’d say this project has passed this test with the highest score. We are still in love with the extension 3 years after it has finished. We’ve also received a lot of compliments from our guests.
I highly recommend both Nadir and George for their service.
