Garden annexes in Huyton

We take on garden annexes in Huyton as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Huyton

Huyton sits 6 miles east of Liverpool, with Prescot 2 miles to the north-east and Speke 5 miles to the south.

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

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.

  • Foundations and drainage connections
  • Brick, block or timber-frame structure
  • Kitchenette and shower room

How much should I budget for a garden annexe?

Use these ranges to budget for garden annexes; the survey turns them into a fixed price for the agreed specification.

Garden annexesGuide 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

What approvals does a garden annexe need in England?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

A self-contained annexe used for sleeping and living normally needs planning permission in England.

What can affect a garden annexe?

  • 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 people ask before starting

Do I need planning permission for a garden annexe?

Usually yes, because people will sleep in it. Outbuilding permitted development does not cover living accommodation.

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.

Who deals with the council for a project in Huyton?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
