Homes in Yorkshire and the Humber
Across Yorkshire and the Humber, older stone and brick terraces sit alongside inter-war semis and newer estates, and dormers and rear extensions are designed to suit each.
What does a basement conversion involve?
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.
- Damp and structural survey
- Underpinning or lowering the floor where needed
- Ventilation, heating and electrics
How much should I budget for a basement conversion?
Indicative costs for basement and cellar conversions. London and the South East usually sit towards the top of each range.
| Basement and cellar conversions | Guide price incl. VAT |
|---|---|
| Existing cellar conversion | £1,900 to £3,000 per m² |
| New basement excavation | £4,200 to £6,600 per m² |
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 can change the price or programme?
- 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.
