Wraparound extension in Belvedere
Wraparound extension in Belvedere: an L-shaped extension that fills the side return and runs across the back. We measure the house, show you what the rules allow, price it in writing and build it.
Belvedere is covered from our Greater London round, including DA17, DA18 and SE2. In Belvedere 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 Belvedere?
Planning for a wraparound extension in Belvedere follows the English householder rules.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Belvedere like to extend?
Belvedere is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

FAQ
Wraparound extension questions in Belvedere
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Is it worth it over a side return alone?
If you want a dining table and a sofa as well as the kitchen, usually yes.
Do you handle building control in Belvedere?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Do I need planning permission for a rear extension in Belvedere?
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.
