Wraparound extension in Thame
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Thame and the surrounding area, with one contract from the first survey to building control sign-off.
Thame and its postcode districts OX9 are part of our Oxfordshire coverage. Wraparound projects around Thame often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Thame?
Here is how the rules in England apply to a wraparound extension in Thame.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Thame like to extend?
Commuter semis and detached houses make up much of Thame, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
