Wraparound extension in Whiston
Wraparound extension in Whiston: 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.
Whiston and its postcode districts L35, WA9 and WA10 are part of our Merseyside coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Merseyside where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Whiston?
The planning route for a wraparound extension in Whiston is set by England's householder rules and your council.
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 Whiston like to extend?
Stone and brick terraces are common around Whiston. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
