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.
- Damp and structural survey
- Lightwells and windows for daylight and escape
- Finished floors, walls and ceilings
What is the guide price for a basement conversion in Largs?
What basement and cellar conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| Basement and cellar conversions | Guide price incl. VAT |

What approvals does a basement conversion need in Scotland?
Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.
In Scotland new basements and external lightwells normally need planning permission; all basement work needs a building warrant first.
What should I think about before starting?
- Groundwater levels drive the waterproofing design and cost.
- A pump for the drainage system needs a battery back-up.
