Basement and cellar conversions in Golborne

Homeowners in Golborne can get basement and cellar conversions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Golborne

Alongside Golborne, we also cover Newton-le-Willows, Ashton-in-Makerfield (2 miles to the west) and Leigh.

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 is included in a basement conversion in Golborne?

Everything below ground depends on keeping water out. We design the waterproofing system (usually a cavity drain membrane with a pump, or tanking) to the relevant British Standard guidance, then add insulation, ventilation, light and an escape route. New basements involve underpinning and a party wall process and are designed with a structural engineer.

  • Waterproofing design and installation
  • Lightwells and windows for daylight and escape
  • Ventilation, heating and electrics

What approvals does a basement conversion need in England?

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.

Converting an existing cellar with no external changes usually does not need planning permission in England.

What should Golborne homeowners check first?

  • A pump for the drainage system needs a battery back-up.
  • Headroom of about 2.1 m or more is needed, which may mean lowering the floor.

How does the project run?

  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. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
