What is a Flat Pack Container Office?
Definition: A flat pack container office is a prefabricated, modular office building that ships flat-packed and assembles on-site in 2-4 hours. It combines a 2.0mm galvanized steel frame (160x160mm columns) with 50mm rock wool sandwich panel walls, delivering an insulated, fireproof and secure workspace. Also known as: flat pack office container, detachable container office, or portable modular office.
Product overview
This model is engineered for construction sites, mining camps and remote project offices that need a durable workspace fast. The fully bolted frame (top/bottom rails, 160x160mm galvanized columns, high-strength carriage bolts) is electrostatically powder-coated for 5-year color retention, while the 50kg/m³ rock wool wall panels provide A-grade fire performance — a key requirement for occupied office spaces.
Office layout
The standard unit offers approximately 17.8 m² of open office space (5950 x 3000 mm internal), with:
- 925x2030mm steel door with integrated frame and handle lock
- 925x1200mm PVC security window (3mm single glass, anti-theft bars)
- 18mm MgO floor board ready for carpet, vinyl or direct use
- Complete electrical package: LED lighting, outlets and wiring
- Optional partitions for meeting rooms, interview rooms or storage

FAQ
What is a flat pack container office?
A flat pack container office is a prefabricated modular building that ships in flat-packed components and assembles on-site in 2-4 hours into a ready-to-use office. It uses a 2.0mm galvanized steel frame with 50mm rock wool sandwich panel walls, providing an insulated, fireproof 17.8 m² working space.
How much does a flat pack container office cost?
Pricing ranges from $1,050 to $2,600 depending on configuration, including the complete structure with walls, roof, floor, door, security window and electrical wiring. Partitioned layouts, plumbing and interior fit-outs add 15-30%.
How is it different from a converted shipping container office?
A purpose-built flat pack container office is lighter, cheaper to ship, better insulated (50mm rock wool vs. spray foam) and arrives with new electrical and finishes — rather than a used steel box requiring costly modification. Assembly requires no welding or cranes.
Can it be stacked or joined for larger offices?
Yes. Units stack up to 3 floors with structural reinforcement, or join side-by-side for open-plan layouts. Internal partitions and extra doors/windows are available on request.
What is the lead time and shipping cost?
Standard lead time is 7-15 days after deposit. Flat-pack shipping runs roughly $500-1,000 to Southeast Asia, $800-1,500 to Africa, and $1,500-2,500 to Europe per 40ft container (approx. 6-8 units per container).
