If you’re feeling a little cramped in your home but love where you live, wraparound extensions—or L-shape extension—could be the perfect solution. This style of extension wraps around the side and rear of your property, giving you the best of both worlds by expanding multiple areas of your home. Whether you want a larger kitchen, more living space, or a home office, a wraparound extension can make it happen, all without having to move house.
A wraparound extension combines a single storey side return and a rear extension into an L-shaped layout, making it ideal for homes in urban areas like London where space is at a premium. It can add valuable square footage to both the back and side of your home, which is particularly useful if your property sits on a corner plot or has space on the side.
Wraparound extensions are especially popular in London & Surrey because they allow homeowners to maximise the use of their plot without extending upwards or outwards into the garden too much. It’s like creating a seamless flow from one part of the house to another, without cutting into outdoor space more than necessary. Plus, they often give homes a much more open-plan feel, perfect for modern living.

In most cases, you will need planning permission for a wraparound or L-shape extension in London, as it alters both the side and rear of the house. However, depending on the size of your planned extension, you might be able to proceed under permitted development rights, which don’t require full planning permission. If the extension is within certain limits (e.g., no more than 3 metres from the rear wall and not taller than 4 metres), you could sidestep planning approval.
It’s always worth checking with your local council or on the planning portal to clarify if your project falls under permitted development. Alternatively, an architectural practice like DeVis Architecture can help guide you through the process, making sure all regulations are met and paperwork & planning permission drawings are properly handled.

A double storey wraparound extension offers incredible potential to maximise your space. It gives you not just one but two floors of extra room. This type of extension is perfect if you need additional living space on the ground floor. Uses include a larger kitchen or open-plan area, while also adding extra bedrooms or a bathroom upstairs.
Not only does a two storey wraparound extension significantly increase your home’s square footage, but it also enhances its overall value. By seamlessly blending with the existing structure, this extension creates a natural flow throughout the house, offering flexibility in design and layout.

House extension cost is always a key factor when considering a home extension, and wraparound extensions in London can vary in price depending on size, design, and materials. As a rough estimate, the cost of a wraparound extension typically starts from ÂŁ70,000 and can rise depending on the size complexity of the project.
High-end finishes, bespoke features, and additional structural work will naturally add to the total. Keep in mind that the cost of planning permission, building control, and professional fees will also need to be factored into your budget.
One of the most exciting aspects of a wraparound extension is the versatility it offers in design. Here are a few creative ways to make the most of your new space:

Natural light is key in making your extension feel bright and spacious. London homes, especially terraced properties, often suffer from a lack of light, but a well-designed wraparound extension can solve that. Consider adding skylights or a glass roof to flood the new space with sunlight. Bi-fold doors leading to the garden are another great option. They bring the outdoors in and creating a seamless connection between your indoor and outdoor spaces.
