Compact 20ft Design with Expandable Office Space
Traditional shipping containers provide a standardized transportation format but have limited usable interior space when used directly as offices.
This expandable container office uses a folding structure to create a larger workspace after deployment while maintaining a compact configuration during transportation.
When expanded, the unit provides approximately 27.5 m² of floor area, allowing the interior to accommodate desks, workstations, storage cabinets, meeting areas, or other project-specific equipment.
This makes it suitable for customers who need more usable space than a standard container office can provide.
700 mm Folded Width for Efficient Transportation
The unit folds to approximately 5900 × 700 × 2480 mm.
The approximately 700 mm folded width helps reduce transportation and storage requirements compared with a fully expanded unit.
For multi-unit projects, the standard loading reference is up to 6 units in one 40HQ container, depending on the final configuration and packing method.
This can be useful for contractors, construction companies, camp operators, project developers, and distributors purchasing multiple units for the same project.

27.5 m² Expandable Office Area
Once expanded, the unit provides approximately 27.5 m² of usable floor space.
The interior can be arranged according to the intended application, including:
- Construction site office
- Project management office
- Engineering office
- Site administration office
- Temporary workspace
- Meeting room
- Reception area
- Worker camp office
- Remote project office
The open layout also allows customers to install their own furniture and equipment according to project requirements.
70mm EPS Insulated Wall Panels
The standard wall system uses 70mm EPS color steel composite panels with an EPS core density of approximately 12 kg/m³.
The insulated panel system provides basic thermal insulation and weather protection for temporary and semi-permanent project facilities.
For projects in different climates or with specific technical requirements, the wall system and other specifications can be discussed before production.
Thermal-Break Aluminum Double-Glazed Windows
The standard configuration uses thermal-break aluminum doors and windows with double glazing.
The door and window arrangement can be customized according to the required office layout, ventilation, natural lighting, access, and project requirements.
Customers can also discuss different window sizes, door positions, and exterior colors for project orders.
Flexible Configurations
The expandable container office can be supplied in different configurations depending on the intended use.
Empty Configuration
The empty configuration provides a flexible open-shell unit for customers who prefer to complete the interior according to their own design, local requirements, or project specifications.
It can be used for:
- Site offices
- Worker accommodation
- Temporary workspaces
- Modular projects
- Distributor projects
Bathroom Configuration
A bathroom configuration is available for projects that require sanitary facilities.
Typical bathroom equipment may include:
- Toilet

Expandable Container Office vs. Standard Shipping Container
A standard shipping container is primarily designed for cargo transportation. When converted into an office, its fixed dimensions limit the available interior space.
An expandable container office provides a different solution: the unit remains compact during transportation and expands at the destination to provide a larger usable workspace.
This makes the design particularly suitable for projects where transportation efficiency and usable floor area are both important.
