What do you get with 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
- Underpinning or lowering the floor where needed
- Finished floors, walls and ceilings
How much should I budget for a basement conversion?

|---|---|
| Existing cellar conversion | £1,900 to £3,000 per m² |

Do you need permission for a basement conversion in Limavady?
Projects in Northern Ireland need planning clearance from one of the eleven councils and building control approval, also from the council. The Party Wall etc. Act does not extend to Northern Ireland, so work near neighbours is agreed directly and documented carefully.
In Northern Ireland new basements and external changes normally need planning permission; building control approval is needed.
What should Limavady 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.
What happens after I enquire?

- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
