How is a basement conversion approved in Houghton-le-Spring?

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.

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?

  • New basements nearly always involve the Party Wall Act in England and Wales.
  • 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. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
