Homes in Yorkshire and the Humber

Stone-built terraces are typical of many West Yorkshire towns, while red brick dominates in Hull and much of South Yorkshire, so matching materials is a big part of designing an extension here.

What goes into a basement conversion?

A basement conversion turns an existing cellar into dry, usable rooms, or excavates a new basement under a house. Converting an existing cellar is far simpler and cheaper than digging a new one, and often does not need planning permission.

  • Lightwells and windows for daylight and escape
  • Ventilation, heating and electrics
  • Finished floors, walls and ceilings

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. Digging a new basement or adding a lightwell often does, and many councils have basement policies.

What should I think about before starting?

  • 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.

What happens after I enquire?

  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. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  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.

Your questions answered

How do you keep a basement dry?

With a designed waterproofing system, usually a cavity drain membrane draining to a pump, sometimes combined with tanking.

Will my neighbours be affected?

New basements usually need party wall agreements. We handle the notices and surveyors.

Can you visit a house in Driffield to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
