Before your single-storey extension in Stratford-upon-Avon
Before work starts on your single-storey extension in Stratford-upon-Avon, two things get checked: whether planning permission from Stratford-on-Avon District Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.
- Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.
- A lawful development certificate from Stratford-on-Avon District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.
- Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.

Choices to weigh up in Stratford-upon-Avon
Flat roof or pitched roof
Flat roofs, usually GRP fibreglass or EPDM rubber, keep the height down near boundaries and suit roof lanterns. Pitched or lean-to roofs with tiles to match the house look more traditional and shed rain faster, but need more height. The choice affects permitted development limits, cost, and how much light reaches the existing rooms.
Wrap-around extension
Combines a side and rear extension into an L shape, giving the largest ground-floor gain. Because it extends both sideways and rearwards, a wrap-around normally needs a householder planning application rather than relying on permitted development. Expect more steelwork and a more involved roof where the two sections meet.
What does your single-storey extension cost in Stratford-upon-Avon?
Prices in Stratford-upon-Avon match the rest of our area: £28,000–£90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: usually £40,000–£52,000.
| Option | Guide price | Good to know |
|---|---|---|
| Small rear or side extension (10–15 m²) | £28,000 – £40,000 | Utility, WC or a modest kitchen extension |
| Rear kitchen-diner extension (18–25 m²) | £38,000 – £58,000 | The glazing spec moves it within the range |
| Wrap-around or large extension (30 m²+) | £58,000 – £90,000 | More steel and roof, and normally a planning application |
Guide ranges include VAT where it applies. Access, parking and the state of what's there now can move the price — the survey settles it.
