The 4 × 4 m side-linked flat-pack storage container combines two 4 × 2 m modules to create one large, open-plan storage space with approximately 16 m² of nominal floor area.
The adjoining side panels are omitted, and the two modules are securely connected using a purpose-designed side-by-side linking kit. The result is one integrated storage structure without a complete internal dividing wall.
Its wide, near-square layout is suitable for machinery, commercial inventory, workshop equipment, furniture and bulky goods that require more internal space than a standard-width container can provide.
The dimensions stated on this page are nominal commercial dimensions. Exact external measurements and internal clearances are provided in the technical drawing prepared for the selected configuration.

Complete Side-Linked Container Package
The complete configuration comprises:
- 2 × 4 × 2 m flat-pack storage containers
- 1 × side-by-side linking kit
- Galvanized steel base-frame connection components
- Central roof-support and roof-joint components
- Internal floor-joining components

- Secure outward-opening steel access doors
The components are prepared for the selected configuration and supplied in flat-pack form for assembly and connection at the installation site.
Approximately 16 m² of Open-Plan Storage
Connecting two 4 × 2 m modules side by side creates a substantially wider storage area than a standard flat-pack container. Goods, machinery and equipment can be arranged across the combined width of both units.
The open-plan configuration provides:
- Additional width for bulky and irregularly shaped items
- Easier movement and organisation of stored goods
- Flexible shelving and racking arrangements
- Improved access to machinery and equipment
- Better use of the central floor area
- A modular alternative to permanent storage construction
The near-square footprint provides a versatile internal layout for commercial, industrial and self-storage applications.

Purpose-Designed Side-Linking System
The linking kit connects the two 4 × 2 m modules along their adjoining sides. It integrates the separate base frames, floor sections and roof structures into one modular storage system.
The linking system is designed to:
- Align and secure the two galvanized steel base frames
- Connect the internal floor sections
- Support the central roof connection
- Protect the external roof joint
- Create a continuous internal storage area
- Provide stability at the connection between the modules
The wall panels at the adjoining sides are omitted during installation, allowing the two modules to function as one large storage unit.
Galvanized Steel Construction
The frames, profiled wall panels and linking components are manufactured from galvanized steel. This creates a durable enclosure suitable for commercial, industrial, construction and outdoor storage applications.
Galvanization helps protect the steel against corrosion and changing environmental conditions. The bolted construction system also reduces the need for permanent site welding and supports future dismantling or relocation.
Durable OSB Flooring
Durable OSB panels are installed over the galvanized steel base frames to provide a practical internal storage surface.
A purpose-designed floor connection is fitted where the modules meet, creating a continuous transition across the linked storage area.
Alternative floor finishes may be considered for projects with specific loading, moisture or operational requirements.
Secure and Configurable Access
Outward-opening steel doors provide convenient access without reducing the usable internal floor area. The doors are fitted with lockable hardware suitable for general commercial and self-storage applications.
Available access arrangements may include:
- A primary double-door entrance
- Separate access doors for each original module
- Additional side doors
- Alternative door positions
- Access ramps
- Upgraded locking systems
Door quantity and position should be confirmed before manufacturing so that the structural frame and panel arrangement can be prepared correctly.
Available RAL Colour Options
The 4 × 4 m side-linked flat-pack storage container can be supplied in a range of powder-coated RAL colours to match company branding, project requirements or the visual design of a self-storage facility.

Typical Applications
The large, open-plan configuration is suitable for:
- Self-storage facilities
- Commercial stock and inventory
- Machinery and maintenance equipment
- Construction tools and materials
- Industrial supplies
- Workshop equipment
- Furniture and household contents
- Landscaping machinery
- Agricultural tools and supplies
- Sports and event equipment
- Spare parts and packaged goods
- Remote project storage
XL Unit for Self-Storage Facilities
The 4 × 4 m configuration can be offered as an XL or premium unit within a commercial self-storage facility.
It is particularly suitable for customers storing:
- Household furniture and contents
- Business inventory
- Tools and trade equipment
- Seasonal commercial stock
- Renovation materials
- Event and exhibition equipment
- Bulky or irregularly shaped goods
Combining standard and linked units within the same facility allows operators to provide different storage capacities for residential and commercial customers.
Efficient Flat-Pack Transportation and On-Site Assembly
Both 4 × 2 m modules are supplied in flat-pack form rather than as one fully assembled oversized structure.
This reduces transportation volume and allows the individual components to be moved to the installation area before assembly. The system is particularly suitable for:
- Narrow site entrances
- Enclosed storage yards
- Locations behind existing buildings
- Construction compounds
- Industrial facilities
- Remote project locations
- Sites with limited lifting access
- International export shipments
Once the components reach the prepared installation area, the two modules are assembled, aligned and connected using the matching side-linking kit.

Frequently Asked Questions
How is the 4 × 4 m side-linked flat-pack storage container created?
It is formed by positioning two 4 × 2 m flat-pack storage containers side by side. The adjoining wall panels are omitted, and the modules are connected using a purpose-designed linking kit.
Is there a dividing wall between the connected modules?
No complete dividing wall is installed at the connection. The adjoining side panels are omitted to create one continuous, open-plan storage space.
Is the exact external width 4 metres?
The 4 × 4 m designation is the nominal commercial size. The exact external width may be greater because of the steel frames, wall profiles, roof projections and linking components. Final measurements are provided in the technical drawing.
Can additional access doors be installed?
Yes. Additional doors and alternative door positions can be prepared when specified before manufacturing.
Can shelving and storage racks be added?
Yes. Shelving and racking can be supplied according to the intended goods, available internal space and required storage layout.
Can the container be dismantled and relocated?
Yes. The bolted modular system can be dismantled, transported and reassembled, subject to the condition of its components and the requirements of the new installation site.
Can additional modules be connected?
Additional compatible modules may be incorporated following a technical review of the proposed configuration, installation site and intended use.
