Louise’s choice: SIDE EXTENSION
Turn wasted space in your side return into a flexible living area with this handy extension guide, including cost, building and more
For many homeowners, the side return area – the strip of land that runs alongside the ground floor, often in a Victorian terraced house – is a redundant space. But by building an extension on it and squaring off the L-shaped property, you can make your home bigger and better.
COMPARED TO OTHER EXTENSIONS, A SIDE RETURN TENDS TO USE UP R EDUNDANT ‘DEAD SPACE’, RATHER THAN THE BEST PARTS OF YOUR GARDEN
How much will it cost?
A side extension design will cost anything from £20,000 to £50,000, depending on the area you live, how large the extension, design complexity, which contractors you use and the building materials. Also factor in internal work, such as adding a kitchen, and the style of the extension.
What work is involved?
A new wall is built on either the boundary of you and your neighbour’s land, or solely on your side of the boundary. A roof is added and the side wall to the existing rear room is either completely or partially knocked through. A steel frame may need to be inserted in the wall to support this new opening plus a new floor, level with the existing floor.
Will I need an architect?
Not necessarily. Some conservatory companies and specialist builders offer a ‘design and build’ package service, which saves paying fees to architects or structural engineers. However, by handling your planning application, an architect gives you a good chance of success.
Do I need permission?
You no longer need planning permission for a ground floor side extension under permitted development as long as it complies with set criteria. You’ll still have to comply with Building Regulations and with the Party Wall Act, so speak to your local council’s planning office for details.
How long will it take?
Plan for at least eight to ten weeks for the structural work, plus more for decorating the interior. Timings can vary, depending on the complexity of your project.
