Two-storey rear extension in Shrewsbury
For homes in Shrewsbury, 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.
Shrewsbury sits in Shropshire, with postcode districts including SY1, SY2 and SY3. Two-storey rear extensions suit semi-detached houses in Shrewsbury best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Shrewsbury?
Planning for a two-storey rear extension in Shrewsbury follows the English householder rules.
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 Shrewsbury like to extend?
Shrewsbury has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ
Two-storey rear extension questions in Shrewsbury
How much does a two-storey rear extension cost in Shrewsbury?
As a guide, £1,800–£2,700 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £54,000–£81,000 at that rate. Your written price follows the survey.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
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.
Can you match the brick or stone on my Shrewsbury house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Do you handle building control in Shrewsbury?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
