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
- Brick, block or timber-frame structure
- Heating, hot water and electrics

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?
- 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.
