Buy or rent your site cabin?
Rental: for a specific project
If you need it for the duration of one project, rental avoids the upfront investment. We bring the cabin at the start of the works and collect it when you finish.
Purchase: if you run one site after another
If your company works on several sites a year, buying the units is more cost-effective: you move them from one site to the next with our crane truck transport.
- As a guide, 12 to 24 months of rental usually equals the purchase price.
- We help you work out which option makes sense in your case.
