What goes into 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.
- Building warrant application and completion certificate
- Waterproofing design and installation
- Underpinning or lowering the floor where needed
What will a basement conversion cost?
Use these ranges to budget for basement and cellar conversions; the survey turns them into a fixed price for the agreed specification.
| 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 |
Planning and building rules in Cumbernauld
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 Cumbernauld homeowners check first?
- Groundwater levels drive the waterproofing design and cost.
- Headroom of about 2.1 m or more is needed, which may mean lowering the floor.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Basement and cellar conversions: common questions
Does a cellar conversion need planning permission?
Usually not if nothing changes outside. New basements and lightwells often do.
How long does it take?
About 6 to 12 weeks for a cellar conversion and 16 to 30 weeks for a new basement.
Can you visit a house in Cumbernauld to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
