Single-storey extensions in Leighton Buzzard

We take on single-storey extensions in Leighton Buzzard as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Leighton Buzzard

Our coverage around Leighton Buzzard (LU7) also includes Dunstable, Bletchley and Milton Keynes.

Homes in the East of England

Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.

What is included in a single-storey extension in Leighton Buzzard?

We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.

  • Planning or lawful development certificate where needed
  • Brickwork, roof, glazing and insulation
  • First-fix and second-fix electrics, plastering and making good

What will a single-storey extension cost?

Use these ranges to budget for single-storey extensions; the survey turns them into a fixed price for the agreed specification.

Do you need permission for a single-storey extension in Leighton Buzzard?

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.

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 can affect a single-storey extension?

  • Building on or near a shared boundary usually means serving a party wall notice in England and Wales.
  • Kitchens and doors have long lead times, so we order them early.

Your questions answered

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.
