Do you need planning permission for a wraparound extension in Ascot?
The planning route for a wraparound extension in Ascot is set by England's householder rules and your council.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
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 Ascot like to extend?
Commuter semis and detached houses make up much of Ascot, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Wraparound extension questions in Ascot
Do you handle building control in Ascot?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can you match the brick or stone on my Ascot house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
Do I need planning permission for a rear extension in Ascot?
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.
What postcode areas do you cover around Ascot?
Including SL5, and the surrounding Berkshire area.
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.
