Two-storey rear extension in Crumpsall
We plan and build two-storey rear extensions for homeowners in Crumpsall. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Start with a free site visit, then a written price once the design is agreed.
We cover Crumpsall (M4, M8 and M9) as part of our Greater Manchester work. Two-storey rear extensions suit semi-detached houses in Crumpsall best, where the extra bedroom matters as much as the bigger kitchen.

How much does a two-storey rear extension cost in Crumpsall?
For Crumpsall we work from the North West England rate: £1,690–£2,540 per square metre of new floor, including VAT, standard specification. North West prices sit below our West Midlands baseline; access on terraced streets is the main variable.

| 4 m × 6 m footprint, two floors (48 m²) | £81,000–£122,000 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a two-storey rear extension in Crumpsall?
Whether your two-storey rear extension in Crumpsall needs a planning application depends on its size, your house and any local restrictions.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Crumpsall like to extend?
Crumpsall has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.
