Covering Yeovil
Our coverage around Yeovil (BA20) also includes Bridport (15 miles to the south) and Dorchester.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
What do you get with a garden annexe?
A garden annexe is a separate single-storey building in the grounds of a house with its own bedroom, bathroom and kitchenette, used by family members as part of the main household. Unlike a garden office, an annexe that people sleep in normally needs planning permission and full building regulations approval.
- Foundations and drainage connections
- Brick, block or timber-frame structure
- Accessible design options for older relatives
What will a garden annexe cost?
Use these ranges to budget for garden annexes; the survey turns them into a fixed price for the agreed specification.
| Garden annexes | Guide price incl. VAT |
|---|---|
| Standard specification | £2,400 to £2,900 per m² |
| Good specification | £2,900 to £3,400 per m² |
| High specification | £3,400 to £3,900 per m² |
Do you need permission for a garden annexe in Yeovil?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
A self-contained annexe used for sleeping and living normally needs planning permission in England. Permitted development for outbuildings does not cover living accommodation.
What should Yeovil homeowners check first?
- Drainage may need a pump if the garden falls away from the sewer.
- A level threshold and wider doors make the annexe suitable for later life.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Questions about a garden annexe in Yeovil
Can I rent the annexe out?
Usually not without a separate planning permission, because councils normally require it to stay part of the main house.
Can you make it wheelchair accessible?
Yes. Level access, wider doors and a level-access shower can be designed in from the start.
Do you work in Yeovil?
Yes. Yeovil is within our coverage for garden annexes, along with nearby Bridport and Dorchester.
