Covering The Highlands
Our basement and cellar conversions service in the Highlands covers Inverness, Fort William, Nairn and Thurso and more.
Because the Highlands covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in the Highlands
Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.
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 the Highlands?
Typical ranges for basement and cellar conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| 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 Scotland?
Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.
In Scotland new basements and external lightwells normally need planning permission; all basement work needs a building warrant first.
What should the Highlands 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.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
