Detailed Description
The 20ft Open Plan Office Container is converted from a standard shipping container to create a functional workspace. Its primary structure remains the robust steel frame, originally engineered for maritime transport, which offers significant durability for ground-level use . A key functional feature is its open-top design, which can facilitate the loading of taller equipment or materials if the unit is being used for combined storage and workspace purposes, although for office use, a permanent roof structure is installed or the tarpaulin cover is replaced with a solid insulated roof during modification .
The open floor plan maximizes the available interior space, which is approximately 150 square feet . This clear span allows for flexible layout configurations. Depending on the level of fit-out, the interior can accommodate desks, meeting areas, and filing systems. Standard modifications often include the installation of windows for natural light, a personnel door for entry and exit, and electrical rough-ins for lighting and power . The steel construction provides a high level of security for sensitive documents and equipment left on-site .
Furthermore, units of this type are frequently fitted with insulation materials such as polyurethane foam (PUF) panels or fiberglass to regulate internal temperatures, making the environment more suitable for personnel . The exterior is typically finished with a primer and durable paint coating to prevent corrosion. By repurposing a shipping container, this office space offers a practical alternative to traditional construction, often with a faster deployment timeline .

Intended Applications
This container office is suited for a variety of professional settings. It is commonly utilized on construction sites as a project management office or a secure tool and equipment check-in point . It can also function as a security checkpoint, a satellite office for remote operations, a temporary retail space, or a workshop for small-scale maintenance tasks . Its modular nature allows it to be used as a single, self-contained unit or combined with other containers to form larger, multi-room complexes.

Dimensions and capacity

Internal dimensions are approximately 19 ft 4 in × 7 ft 8 in × 7 ft 10 in (5,898 × 2,350 × 2,393 mm), giving 1,170 cu ft (33.1 m³) of usable space, with double doors at one end. These are the standard figures for a 20ft container; exact internals vary slightly by manufacturer.

Condition

This is a used container that has been in service. It is wind and watertight — no holes, working door seals, an intact roof — but it shows its history: surface rust, dents and previous owner markings are normal and do not affect how it performs.

What it is good for

This unit is commonly used for a fitted-out working space. Doors, windows, insulation, electrics and paint can all be added before it ships — it is cheaper and neater to specify a conversion while the container is still in our yard than to modify it on your site afterwards.

Standards and inspection

Containers intended for international shipping carry a valid safety approval plate under the Convention for Safe Containers, administered by the International Maritime Organization. Condition grades such as cargo-worthy follow the inspection criteria published by the Institute of International Container Lessors. If you need a unit for shipping rather than static storage, tell us and we will confirm its plate before dispatch.

Delivery

Delivery is quoted against your site access rather than published as a flat rate, because haulage for a container depends on the distance, the approach and whether a crane is needed. Most deliveries use a tilt-bed truck, which needs a clear and reasonably level run about twice the container length. We price it before you commit.
