The 20ft ModiBox Office is our best-selling container office for a simple reason: it fits almost anywhere, costs a fraction of a traditional build and needs nothing more than a power lead to become a working space. Converted from a reinforced steel shipping container, it brings anti-vandal security and genuine weather resistance to sites where a lightweight cabin would struggle. Inside, rockwool insulation and a melamine lining create a bright, warm room for supervisors, inspectors and administrative staff.
Key Features
- Anti-vandal windows with steel shutters, heavy-duty shoot bolts and an anti-vandal lip for secure overnight closure.
- 100mm rockwool insulation behind a melamine panel lining, holding heat in and giving a clean, wipe-down interior finish.
- Full electrical package — double sockets, strip lighting, a wall heater and a consumer unit, so the office runs from a single site hook-up.
- Heavy-duty vinyl flooring, stain and slip resistant, laid over the container deck.
- Steel personnel door with multi-point locking for proper security when the site is unattended.
- Container-grade steel structure that can be craned, stacked and relocated without dismantling.
- Repainted exterior in solvent-free rubberised marine-grade paint, available in a choice of standard RAL colours.

Ideal For
Construction site offices and welfare space, security and gate offices at industrial premises, inspection and coordination points on live projects, sports club and community offices, garden offices at home, and temporary administration during a refit. It also makes a sound long-term office for yards and depots where a permanent building would trigger unnecessary cost and planning work.
Delivery Across the UK
Twenty-foot offices are the most straightforward container to place, and we deliver them nationwide on HIAB or tilt-bed transport. You will need firm, level hardstanding and a clear approach for the vehicle; if access is restricted, ask us about a smaller dedicated lorry. Bear in mind that permanent siting or use in a residential setting may need a word with your local planning department first.
