Looking to enhance the footprint of your property? We’re exploring the benefits of wraparound extensions and what you need to know in terms of planning requirements and cost…
But first, what exactly is a wraparound extension? Also known as an L-shape extension, it is a combination of a side and rear extension with the corner filled in.
If you have the budget and your heart’s desire is a whopping kitchen and living space plus a bootroom, utility space and a pantry, then a wraparound extension could definitely be for you. In the urban Victorian terrace, it can be an interesting way to use dead space – the side return – without nibbling too much into the garden.
Grant Straghan, practice director of Dedraft, has lots of requests for wraparound extensions but admit they are not always popular with planning departments. “Several boroughs are not that keen on this extent of development as it can cause tunnelling for the adjacent neighbour and reduces garden depth and amenity space,” he tells KBB journo Amanda Cochrane.

The cost
As ever, how long is a piece of string? How large is the project in terms of the new footprint? And are you trying to match the fabric of the traditional house, or going for a super-sleek, modern look that creates a beautiful contrast?
“Currently, all extensions from a mid to high spec come in between £3500 to £4500 per square metre excluding VAT,” says Grant. “It is worth noting the choice of kitchen and appliances is the key driver to work out this rate.”
Planning requirements
The wraparound project is going to require more complex design and also planning approval, especially in a conservation area. Under permitted development, you can extend along the side of the house and separately at the rear without planning permission. However, when these two extensions are joined to form an L, then you need planning permission.
You’ll also need to consider issues such as the loss of light and privacy to neighbours, the appearance of the materials you choose, and the impact on the local area.
The benefits
The wraparound extension offers huge flexibility as it can add 15 to 60 sq m of space. This gives you the freedom to add generous kitchen and living spaces plus additional office or recreation areas, or even a downstairs bathroom.
Working well for both traditional homes and more modern builds, the sheer variety of options means serious thought is needed in terms of creating what is, effectively, a completely new flow in your ground floor space. The better you understand your and your family’s lifestyle and needs, the easier it is to future-proof the design.
“The wraparound offers flexibility for family life and, with additional space, there tends to be more spaces to retreat to for each family member,” says Grant. “Homework can be done in the same or adjacent room or nook while others play or watch TV or come and go from the garden with more ease than in more traditional homes.”
