Garden annexes in Cheshire

Covering Cheshire

We cover Cheshire, including Warrington, Chester, Crewe and Ellesmere Port, and the towns around them.

Homes in the North West

The North West has long rows of Victorian terraced houses in its towns and cities, alongside inter-war semis and post-war estates, so rear extensions, dormer lofts and kitchen extensions are common projects.

What is 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.

How much should I budget for a garden annexe?

Indicative costs for garden annexes. London and the South East usually sit towards the top of each range.

Garden annexes	Guide price incl. VAT
Standard specification	£2,400 to £2,900 per m²
Good specification	£2,900 to £3,400 per m²
High specification	£3,400 to £3,900 per m²

How is a garden annexe approved in Cheshire?

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 Cheshire homeowners check first?

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.

What happens after I enquire?

Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

Garden annexes: common questions

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.

Can you make it wheelchair accessible?

Yes. Level access, wider doors and a level-access shower can be designed in from the start.

Do you work in Cheshire?

Yes. Cheshire is within our coverage for garden annexes, along with nearby Warrington and Chester.
