Covering Sutton Coldfield

Sutton Coldfield sits 7 miles north-east of Birmingham, with Aldridge 5 miles to the north-west and Aston 5 miles to the south-west.

Homes in the West Midlands

Across the West Midlands, terraced and semi-detached houses in red brick are typical, along with post-war estates where garage conversions and side extensions are popular.

What does a garden annexe involve?

We design annexes as permanent buildings with proper foundations, insulation and services, and we prepare the planning case showing how the annexe will be used as part of the main home. Connections for water, drainage and power are planned from the start.

  • Design and planning application
  • Foundations and drainage connections
  • Brick, block or timber-frame structure

How much does a garden annexe cost in Sutton Coldfield?

Typical ranges for garden annexes. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

What approvals does a garden annexe need in England?

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 can affect a garden annexe?

  • 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.

How does the project run?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  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.
