Wraparound extension in Roehampton
We plan and build wraparound extensions for homeowners in Roehampton. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
We cover Roehampton (SW13, SW14 and SW15) as part of our Greater London work. In Roehampton we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

Do you need planning permission for a wraparound extension in Roehampton?
Here is how the rules in England apply to a wraparound extension in Roehampton.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Roehampton like to extend?
Much of Roehampton is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley.

FAQ
Wraparound extension questions in Roehampton
Do I need planning permission for a rear extension in Roehampton?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
Can you match the brick or stone on my Roehampton house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
