This 10ft × 10ft high cube mobile office container is one of the most comprehensively specified turnkey office units in our range — a purpose-built modular structure on a reinforced steel frame measuring 10ft × 10ft × 10ft, providing a near-square internal footprint of 9ft 3in × 9ft 3in at an internal height of 9ft 5in. Unlike standard ISO shipping container conversions which are 8ft wide, this unit’s 10ft external width provides a noticeably more spacious interior suited to a proper single-occupancy office setup with a desk, seating, and filing storage without the cramped layout of an 8ft-wide unit. The 10ft external height is taller than a standard ISO high cube (9ft 6in), providing additional ceiling clearance after insulation and drywall reduce the finished internal height.

The insulation system uses a dual-layer approach — ½ inch spray foam applied directly to the steel shell for air sealing and thermal bridging prevention, plus R12 batt insulation in the stud cavities of both ceiling and walls for thermal performance. This combination provides better year-round thermal efficiency than either system alone. The interior is finished with pre-finished drywall panels on steel stud framing with matching trim — a clean, paintable, professional office finish that distinguishes this unit from containers finished in bare steel, plywood, or melamine.

Climate control is provided by a 2000W baseboard heater with thermostat for heating and a 6000 BTU A/C unit for cooling — both US-standard voltage. The electrical system is completed to a 60-amp panel with exterior junction box, four power outlets including a dedicated A/C outlet, and 4ft LED wrap lights for bright, even interior illumination. Natural light is provided by three windows: one 5ft × 3ft, one 7ft × 3ft, and one 2.5ft × 3ft — all three positioned to provide cross-ventilation options. The floor is vinyl plank — moisture-resistant, durable, and easy to clean in a working office environment. The insulated steel personnel door is fitted with hardware, lockbox, and weatherproof seals.
