Two-storey rear extensions in Gloucestershire
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Across Gloucestershire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Gloucester, Cheltenham and Stroud.
Two-storey rear extensions suit semi-detached houses in Gloucester best, where the extra bedroom matters as much as the bigger kitchen. Stone-built and rendered houses are common around Gloucestershire, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
How much does a two-storey rear extension cost in Gloucestershire?
For Gloucestershire we work from the South West England rate: £1,870–£2,810 per square metre of new floor, including VAT, standard specification. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m × 5 m footprint, two floors (30 m²) | £56,000–£84,000 |
| 4 m × 6 m footprint, two floors (48 m²) | £90,000–£135,000 |
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 in Gloucestershire?
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 Gloucestershire?
We cover 10 towns and districts in Gloucestershire, including Gloucester, Cheltenham and Stroud.
