Do you need planning permission for a two-storey rear extension in Wilmslow?
The planning route for a two-storey rear extension in Wilmslow is set by England's householder rules and your council.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
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 Wilmslow like to extend?
Stone and brick terraces are common around Wilmslow. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

Can I get a price without a visit?

Do you handle building control in Wilmslow?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
