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 is 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.
- Waterproofing design and installation
- Ventilation, heating and electrics
- Finished floors, walls and ceilings
What will a basement conversion cost?

What approvals does a basement conversion need in England?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
Converting an existing cellar with no external changes usually does not need planning permission in England.
What should Radcliffe homeowners check first?
- New basements nearly always involve the Party Wall Act in England and Wales.
- A pump for the drainage system needs a battery back-up.
