Garden annexes in Westhoughton

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

Covering Westhoughton

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?

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
  • Heating, hot water and electrics
  • Accessible design options for older relatives

Do you need permission for a garden annexe in Westhoughton?

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. 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.
  • A level threshold and wider doors make the annexe suitable for later life.

What happens after I enquire?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
