Garden annexes in Coventry

Planning garden annexes in Coventry? We design and build them for houses across the West Midlands, and we fix the price for the agreed specification in writing before any building work starts.

Covering Coventry

Coventry sits 17 miles east of Birmingham, with Kenilworth 5 miles to the south-west and Bedworth 5 miles to the north.

Homes in the West Midlands

Red-brick terraces and inter-war semis make up much of the housing in the West Midlands, which suits rear extensions, dormer lofts and hip-to-gable conversions, with more modern estates on the edges of the 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.

  • Brick, block or timber-frame structure

Planning and building rules in Coventry

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 I think about before starting?

  • 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.

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. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
