Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

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.

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

Planning and building rules in Redhill

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

A self-contained annexe used for sleeping and living normally needs planning permission in England.

What should Redhill homeowners check first?

  • 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.

How does the project run?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Garden annexes: common questions

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.

Who deals with the council for a project in Redhill?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
