Overview

Double the workspace of a 20ft on the same width

The 40ft container office is a 12,192 × 2,438 mm portable site office built on a high-cube ISO shell, with about 26 m² of floor space: double the workspace of a 20ft unit on the same width. SCS Global builds it factory-direct at our Yixing, Jiangsu facility as the large format in our container office range from 10ft to 40ft . Like all SCS container offices, it starts as a purpose-built new shell, engineered as an office from the first weld rather than converted from a used box. The extra length buys separation: a 40ft shell partitions into genuine multi-room layouts with independent climate zones, where the standard 20ft site office gives you one room. If the site needs an office and a lunch room on a single delivery, this is the unit.

Specifications

40ft Office Specifications and Dimensions

Externally, the unit runs 12,192 × 2,438 × 2,896 mm on the high-cube shell, the market-standard basis for a 12-metre site office. Budget builds on a standard-height general purpose shell finish at 2,591 mm. Every 40ft container office layout starts from that same envelope: partition positions, door placement, and kitchenette location set the configuration, not the shell. Our engineers turn a marked-up floor plan into a dimensioned 40ft container office design before fabrication starts. Weights and as-lined internal dimensions are category reference figures, confirmed to project requirements at quote stage.

Compliance

Compliance and Standards

The fit-out uses NCC-compliant materials with AS/NZS 3000 electrical work, and plumbed lunch-room and ablution configurations are built to AS/NZS 3500, all on an ISO 668 high-cube shell (1AAA classification, 1AA for the general purpose alternative). Plumbing matters more on the 40ft than any other size in the range: kitchenette water supply and ablution sanitary work both sit under AS/NZS 3500. For Pilbara and North Queensland deployments, tie-down and structural documentation is engineered to AS/NZS 1170.2 wind actions for Region D, and mine-spec builds add exit lighting, illuminated safety signage and smoke alarms, certifiable with engineering documentation.

Configuration Options

Market-Standard 40ft Layouts

Every 40ft site office container layout starts from the same high-cube envelope: partition positions, door placement, and kitchenette location set the configuration, not the shell. Each partitioned zone carries its own lockable steel PA door and its own split system.

Office + Lunch Room

The working default: site administration at one end, a plumbed crib room with kitchenette at the other.

Two Offices

Separate rooms for principal contractor and subcontractor teams, or project managers and site engineers.

Two Lunch Rooms

Staggered meal breaks for larger crews on one delivery.

Open Plan

A single ~26 m² room for inductions, training, or control-room fit-outs.

Office + Storage

A partitioned roller-door storage section beside the workspace.

Office + Ablution

A plumbed ablution zone to AS/NZS 3500 for self-contained deployments.

FAQ

Frequently Asked Questions

The questions procurement and site teams ask most often about the 40ft site office.

What are the dimensions of a 40ft site office?

A 40ft site office measures 12,192 × 2,438 × 2,896 mm externally on the high-cube shell, or 2,591 mm high where built on a standard-height general purpose shell. That gives about 26 m² of floor space, roughly double a 20ft unit on the same 2,438 mm width.

Can a 40ft site office have multiple rooms?

Yes. The shell partitions into four market-standard layouts: office plus lunch room, two offices, two lunch rooms, or open plan, with office-plus-storage and office-plus-ablution splits also available. Each partitioned zone carries its own lockable steel PA door and its own split system, so rooms run independently.

Is one 40ft office better than two 20ft offices?

One 40ft means one delivery, one set of footings, and one power connection. Two 20ft container office units cost more to place but can sit at opposite ends of a site. For joined multi-unit requirements beyond either option, see modular office complexes.

How is a 40ft site office delivered?

By side-loader or crane truck, depending on site access. A 40ft unit is too long for a tilt tray. At 2,438 mm wide it travels as a standard road load without oversize permits, and the recessed air conditioners keep the fitted 40ft shipping container office inside the ISO freight envelope.
