What goes into a single-storey extension?

A single-storey extension adds one level of new floor space to the back or side of a house, usually to open up a kitchen, dining or family room. It is the most common way to gain space without moving, and many can be built without a planning application.

  • Building control application and inspections
  • Brickwork, roof, glazing and insulation
  • First-fix and second-fix electrics, plastering and making good

What approvals does a single-storey extension 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.

In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What should I think about before starting?

  • Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.
  • Kitchens and doors have long lead times, so we order them early.

Single-storey extensions: common questions

Can we stay in the house during the build?

Usually yes. We keep the existing house closed off from the works until the knock-through near the end, and agree a temporary kitchen set-up with you if the kitchen is affected.

Will the brick match?

We source the closest available match for colour, size and texture and agree a sample panel with you before laying.

Who deals with the council for a project in Bartley Green?

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