Single-storey extensions in Bury

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

Covering Bury

We work in Bury (BL9) and the places around it, including Radcliffe, Heywood and Whitefield.

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

What does a single-storey extension involve?

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.

  • Measured survey and design drawings
  • Building control application and inspections
  • Brickwork, roof, glazing and insulation

What will a single-storey extension cost?

Indicative costs for single-storey extensions. London and the South East usually sit towards the top of each range.

How is a single-storey extension approved in Bury?

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.
  • Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.

What are the steps?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Your questions answered

Do I need planning permission for a single-storey extension?

Often not in England, if the extension stays within permitted development limits: 3 m deep on an attached house or 4 m on a detached house, and no higher than 4 m. Larger ones need prior approval or a planning application. Wales, Scotland and Northern Ireland have their own rules.

Do you need to dig up the drains?

Sometimes. If a public sewer runs under the extension, the water company has to agree a build-over or a diversion. We check this at survey stage.

Who deals with the council for a project in Bury?

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