Bungalow rear extension in Atherton
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Atherton and the surrounding area, with one contract from the first survey to building control sign-off.
Atherton is covered from our Greater Manchester round, including M29, M46 and WN7. For Atherton bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Atherton?
Whether your bungalow rear extension in Atherton needs a planning application depends on its size, your house and any local restrictions.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
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 Atherton like to extend?
Stone and brick terraces are common around Atherton. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
