Types of Wrap-Around Extensions
Wrap-around extensions come in several refined configurations, each designed to maximise space and transform the flow of your home. A wrap-around single-storey extension is ideal for creating expansive open-plan layouts, enhancing natural light and garden connectivity.
For homeowners seeking even greater transformation, a 2-story wrap-around extension adds significant vertical and horizontal space, allowing for additional bedrooms, larger kitchens, or luxury multi-functional living zones.

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.
Frequently Asked Questions on Wrap Around Extensions
A wrap-around extension is an L-shaped addition that extends along the side and rear of a property. It provides more living space, improves natural light, and can create an open-plan layout, making your home feel larger and more flexible.
A single-story wrap-around extension adds ground-floor space without affecting the upper levels. It is generally easier to build, can integrate seamlessly with your home’s existing design, and often has less impact on neighbours.
Pricing depends on the size of the extension, the quality of materials and finishes, design complexity, planning requirements, and site conditions such as access and foundations. Every project is unique, so it’s best to get a customised consultation to understand costs for your property
The cost of a wrap-around single-storey extension varies depending on factors like size, materials, and design. A detailed assessment by an architect or builder is the best way to get an accurate estimate.

Planning permission is often required for wrap-around extensions, especially if they are large or two-storey. Some smaller or simpler extensions may fall under permitted development rights, but local council rules vary. Consulting an experienced architect is recommended.
Yes, Wrap-around extensions can be designed for semi-detached or terraced homes. They can use the side return and rear space effectively, while complying with planning and structural requirements.
A well-designed wrap-around extension can increase property value by providing extra living space and improving the home’s layout. The exact value uplift depends on design, location, and how well the extension integrates with the rest of the property.
Studio 20 Architects offers expert guidance throughout the entire project. We handle feasibility, design, planning, and project management, ensuring your wrap-around extension is practical, compliant, and enhances both your living space and property value.
