Homes in the East of England
Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.
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
- Kitchenette and shower room
- Accessible design options for older relatives

Do you need permission for a garden annexe in Stevenage?
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.
What should I think about before starting?
- The annexe normally has to remain part of the main household, not let as a separate home.
- Drainage may need a pump if the garden falls away from the sewer.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
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.
How long does an annexe take to build?
About 14 to 24 weeks on site after approvals.
Can you visit a house in Stevenage to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
