In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.

What goes into 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.

Planning and building rules in Redruth

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 should Redruth 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?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  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.
