The double storey modular box stacks two clear-span floors into one compact footprint, giving you double the usable area without expanding the site.
Our double storey modular box uses a hard-pressed aluminum clear-span frame with no interior poles, so the full floor area stays open for storage, events, or production. Each unit is built to order with PVC covers, galvanized connectors, and the load ratings shown in the specification table below.



Product Overview
- Stack two 10–30 m wide levels up to 12 m tall for up to 600 m² of column-free floor per unit.
- Clad both floors in insulated 50–100 mm sandwich panels for year-round temperature control.
- Connect modules end-to-end or back-to-back to grow capacity in 5 m bay steps.
- Route power, data and plumbing through pre-framed wall channels with no on-site cutting.
- Finish interiors with stairs, mezzanine rails and fire-rated partitions to local code.
