Two-storey rear extensions in Cheshire
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design and build rear extensions across Cheshire, from Warrington and Chester to Crewe, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Two-storey rear extensions suit semi-detached houses in Warrington best, where the extra bedroom matters as much as the bigger kitchen. Stone and brick terraces are common around Cheshire. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
How much does a two-storey rear extension cost in Cheshire?
For Cheshire 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.
| Size | Guide price inc VAT |
|---|---|
| 3 m × 5 m footprint, two floors (30 m²) | £51,000–£76,000 |
| 4 m × 6 m footprint, two floors (48 m²) | £81,000–£122,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Cheshire?
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.

FAQ
Questions people ask
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
Do you cover all of Cheshire?
We cover 21 towns and districts in Cheshire, including Warrington, Chester and Crewe.
