Covering Kent
Our coverage across Kent includes Maidstone, Gillingham, Chatham and Tunbridge Wells.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What is 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.
- Kitchenette and shower room
- Heating, hot water and electrics
- Accessible design options for older relatives
What will a garden annexe cost?
Indicative costs for garden annexes. London and the South East usually sit towards the top of each range.
| 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 |
How is a garden annexe approved in Kent?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
A self-contained annexe used for sleeping and living normally needs planning permission in England.
What can change the price or programme?
- The annexe normally has to remain part of the main household, not let as a separate home.
- Council tax treatment depends on who lives there; check with your council.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
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.
How do I get a price for garden annexes in Kent?
Use the guide price tool for a ballpark figure, then book a visit for a fixed written price for the agreed specification.
