Will the council need to approve it?
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
Is a single-storey extension right for your house?
- Semi-detached and detached houses with a usable rear garden

Extensions in and around Stroud
Across GL5, GL6, we can visit, measure and advise. Neighbouring towns we cover include Dursley (8 miles), Gloucester (8 miles), Cirencester (10 miles), Cheltenham (12 miles).
Ross-on-Wye, in Herefordshire, is roughly 20 miles from Stroud and also on our list. In the South West, local stone, render and brick vary from town to town, so matching materials is a big part of designing an extension that looks right.

Your questions about a single-storey extension in Stroud
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Stroud, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Stroud?
Yes. We cover Stroud and the surrounding parts of Gloucestershire. Site visits are free and there is no obligation.
Do I need building regulations approval in Stroud?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does a single-storey extension cost per square metre?
Our guide range is about £1,780 to £3,470 per m² including VAT, depending on specification. A standard-spec 4 m × 5 m room usually lands at £41,500 to £53,500 in Stroud, plus design and council fees.
How deep can a single-storey rear extension be without planning permission?
In England, up to 3 m beyond the original rear wall on a semi-detached or terraced house and 4 m on a detached house, within height and boundary limits. Through the larger home extension prior approval scheme those depths rise to 6 m and 8 m. Wales, Scotland and Northern Ireland use their own rules, which we check for your address.
