Two-storey rear extension in Hollinwood
For homes in Hollinwood, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
We cover Hollinwood (M35, OL8 and OL9) as part of our Greater Manchester work. Two-storey rear extensions suit semi-detached houses in Hollinwood best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Hollinwood?
The planning route for a two-storey rear extension in Hollinwood is set by England's householder rules and your council.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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 Hollinwood like to extend?
Stone and brick terraces are common around Hollinwood. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
