What is included in a garden annexe in West Bromwich?

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.

What approvals does a garden annexe need in England?

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 affect a garden annexe?

  • The annexe normally has to remain part of the main household, not let as a separate home.
  • Drainage may need a pump if the garden falls away from the sewer.

  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
