Garden annexes in Stowmarket

We take on garden annexes in Stowmarket as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Stowmarket

Our coverage around Stowmarket (IP14) also includes Ipswich (11 miles to the south-east) and Bury St Edmunds.

Homes in the East of England

The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.

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.

  • Brick, block or timber-frame structure
  • Kitchenette and shower room
  • Accessible design options for older relatives

What is the guide price for a garden annexe in Stowmarket?

How is a garden annexe approved in Stowmarket?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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 Stowmarket homeowners check first?

  • The annexe normally has to remain part of the main household, not let as a separate home.
  • A level threshold and wider doors make the annexe suitable for later life.

How does the project run?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
