What goes into 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.
- Planning and building regulations checks under Welsh rules
- Design and planning application
- Brick, block or timber-frame structure
What will a garden annexe cost?
Guide prices for garden annexes, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| 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 |
What approvals does a garden annexe need in Wales?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
What can change the price or programme?
- Drainage may need a pump if the garden falls away from the sewer.
- Council tax treatment depends on who lives there; check with your council.

Your questions answered
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.
Can you visit a house in Colwyn Bay to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
