Side return extension in Sevenoaks

How much does a side return extension cost in Sevenoaks?

A side return extension in Sevenoaks is priced at £2,580–£4,260 per square metre including VAT as a guide, before kitchen fit-out and fees. South East prices run above our West Midlands baseline, mainly on labour rates and clay-soil foundations.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a side return extension in Sevenoaks?

Here is how the rules in England apply to a side return extension in Sevenoaks.

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 Sevenoaks like to extend?

Commuter semis and detached houses make up much of Sevenoaks, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
