Covering Muswell Hill
We work in Muswell Hill (N2, N10) and the places around it, including Wood Green, Archway and Finchley.
Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
What does a garden annexe involve?
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.
- Design and planning application
- Brick, block or timber-frame structure
- Accessible design options for older relatives

|---|---|
| Standard specification | £2,400 to £2,900 per m² |

How is a garden annexe approved in Muswell Hill?
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 can change the price or programme?
- 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?
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
