Single-storey extensions in Denton

Homeowners in Denton can get single-storey extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Denton

Our coverage around Denton (M34) also includes Hyde, Dukinfield and Droylsden.

Homes in the North West

Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.

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.

  • Planning or lawful development certificate where needed
  • Foundations, drainage and structural steel
  • First-fix and second-fix electrics, plastering and making good

Planning and building rules in Denton

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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.

What should I think about before starting?

  • Drains under the footprint may need diverting or a build-over agreement with the water company.
  • Building on or near a shared boundary usually means serving a party wall notice in England and Wales.

From first call to completion

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
