How much does a mezzanine floor cost?
A storage mezzanine of around 50 m² is published at roughly £8,000–£12,000 supplied and installed. Office mezzanines cost more because they need fire protection, better stairs and a finished floor.
| Item | Typical cost |
|---|---|
| Industrial or commercial mezzanine, structure | £75–£150 per m² [1] |
| Storage mezzanine, about 50 m² | £8,000–£12,000 [2] |
| Office mezzanine, 100 m², fire protected (structure only) | £25,000–£45,000 [2] |
| Fully fitted office floor with fire protection | £450+ per m² [2] |
Worked example. A 100 m² storage floor at £75–£150 per m² is roughly £7,500–£15,000 for the structure. Stairs, pallet gates and any fire protection are on top.
What changes the price
- Floor area and the load it needs to carry
- Use: storage floors are cheaper than office floors
- Fire protection, which office and most working floors need
- Number of staircases and pallet gates
- Fit-out on top: partitions, ceilings, lighting, heating
Rules to budget for
Most mezzanines need Building Regulations approval covering structure, fire and means of escape. Office and working mezzanines must be fire rated; some smaller storage floors may not need to be. Planning permission is sometimes needed, so check with your council.
