Garden annexes in Weymouth

From the first site visit to the final building control sign-off, we manage garden annexes in Weymouth so you only have one company to deal with.

Covering Weymouth

Weymouth is about 7 miles south of Dorchester. We also cover Dorchester (7 miles to the north), Bridport and Poole.

Homes in the South West

Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.

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
  • Foundations and drainage connections
  • Heating, hot water and electrics

How is a garden annexe approved in Weymouth?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

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 change the price or programme?

  • 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.

From first call to completion

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. 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.

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 Weymouth?

Yes. Weymouth is within our coverage for garden annexes, along with nearby Dorchester and Bridport.
