Two-storey rear extension in Bury
Two-storey rear extension in Bury: a larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We measure the house, show you what the rules allow, price it in writing and build it.
Bury is covered from our Greater Manchester round, including BL8, BL9 and M26. In Greater Manchester we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Bury?
Planning for a two-storey rear extension in Bury follows the English householder rules.
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 Bury like to extend?
Stone and brick terraces are common around Bury. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
