Across the East Midlands you find everything from city terraces to modern estates and stone villages, so the right extension depends a lot on the street and the materials around it.

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.

  • Design and planning application
  • Brick, block or timber-frame structure
  • Heating, hot water and electrics

What will a garden annexe cost?

Guide prices for garden annexes, including VAT where it applies. Your fixed price is confirmed in writing after the survey.

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. Permitted development for outbuildings does not cover living accommodation.

What should Retford 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.
