Delivery and placement
Standard containers are delivered using hiab crane vehicles. A 20ft-32ft delivery vehicle requires a minimum width of 10ft and vertical clearance of 15ft. Placement must be on firm, level ground (concrete, tarmac, or gravel) to ensure the structure remains square. This is especially critical for 24ft - 32ft modular units, where uneven surfaces can cause misalignment between windows and personnel doors. For more information, see our about us page.
Frequently asked questions
Which size is best for a site office?
For a small team, a 20ft office is standard. For larger projects requiring split storage and workspace, the 24ft or 32ft units are preferred.
Can these units be stacked?
Yes, our 20ft ISO units are designed for multi-level stacking. Modular units can also be stacked to create multi-storey site complexes when using the correct twistlock connectors.
