Overview
Engineered around your floor plan and fitout brief
A custom container office is engineered around your floor plan and fitout brief. Partition layouts, wet areas, electrical, insulation and climate control are set at the design stage, then built factory-direct on 10ft, 20ft and 40ft ISO container platforms and shipped worldwide. Standard units from our container office range cover most site requirements. Custom design exists for the briefs they can't fit. Every configuration is quoted per project, starting with an engineering assessment.
Fitout Menu
Fitout Options and Configurations
Fitout options cover the full interior and exterior system: wet areas, electrical and data, climate control, doors, windows, security hardware, access and branding, all configured and installed at the factory before the unit ships. A prefab container office leaves the production line as a finished workspace rather than a shell plus a local trades list. One supplier holds the design, the build and the quality records. The menu below shows the configuration axes SCS quotes against. Any combination that fits the platform builds as one unit.
| Specification | Value |
|---|---|
| Layout | Partition walls, multi-room and split-level layouts, desks, shelving and storage, internal linings |
| Wet areas | Kitchenette (sink, hot and cold water, stainless bench), toilet, ensuite, shower, washbasin, eye-wash stations |
| Electrical and data | Switchboard with RCDs, LED lighting, GPO outlets, three-phase outlets, data and communications cabling |
| Climate | Reverse-cycle split-system air conditioning, exhaust fans, solar or whirlybird roof vents, EPS to PIR insulation upgrades |
| Doors and windows | Lockable PA door and sliding window with security (standard), deadlocked personnel doors, side-opening and glass sliding doors, roller shutters, large windows, skylights, lockable servery windows, security mesh, window bars, shutters |
| Access and exterior | External stairs, access ramps, custom painting and branding in corporate colours and logos |
| 10ft platform | 2,991 × 2,438 mm external footprint, ~6.7 m² typical office floor area |
| 20ft platform | 6,058 × 2,438 mm external footprint, ~12 m² typical office floor area |
| 40ft platform | 12,192 × 2,438 mm external footprint, ~26 m² typical office floor area |
| Shell heights | GP shells 2,591 mm, High Cube 2,896 mm (ISO 668) |
Design
Custom Shipping Container Office Design
A custom shipping container office is designed to a documented floor plan before manufacture. Room count, partition positions, door and window placements and fitout level are fixed at the drawing stage, not cut into a finished box after delivery. Layouts run from a single room to multi-room and split-level designs. Common briefs: site administration offices, first-aid and induction rooms, training rooms. Each design starts from an ISO 668 envelope, giving roughly 6.7 m² on a 10ft platform to 26 m² on a 40ft. If a stock layout fits, the standard 20ft and 40ft pages carry full specifications: this page covers everything those layouts can't.
Insulation & Climate
Insulation and Climate Control
SCS fits 50mm EPS wall and ceiling panels as standard, PIR fire-rated on mine-spec builds, and sizes reverse-cycle air conditioning to the insulated unit. An insulated site office container holds a working temperature where a bare steel shell cannot, and a container office with aircon is the default configuration: a 7kW split system cools the unit. A container office with toilet removes the walk to shared site ablutions, a container office with bathroom adds shower and hot water in the same footprint, and plumbed configurations are specified to AS/NZS 3500.
Compliance
Compliance and Certification for Custom Builds
Custom builds are specified to the deployment market's standards: AS/NZS 3000 electrical, AS/NZS 3500 plumbing on wet-area configurations and NCC-compliant materials on standard commercial builds and above, all on ISO 668 and ISO 1496 donor shells. CSC applies in international transport, and cutting apertures affects the plate, so SCS addresses transport certification at the design stage, not after the build: the 10ft joinable pair, CSC-plated as a single 20ft High Cube, shows the approach. Mine-spec builds carry full Australian Standard mine-spec electrical, and builds to DNV specifications sit under our DNV offshore containers range, not as custom office variants.

ABS Fitout Tiers
The Three-Tier Fitout Ladder
Fitout level follows a three-tier ladder, from entry-level builds to full mine-spec. Each tier below lists what the build includes. Specifications conform to industry standards (ISO, AS/NZS, DNV where applicable); confirm to project requirements.
Standard Commercial
One-trip or near-new donor shell, 50mm EPS walls and ceiling, vinyl flooring, full AS/NZS 3000 electrical fitout, reverse-cycle air conditioning standard, NCC-compliant materials, certifiable with engineering documentation.
Mine-Spec
Purpose-built new High Cube shell, 50mm fire-rated PIR, 150mm coved commercial vinyl, mine-spec electrical, Daikin split-system, smoke alarms, exit lighting and illuminated safety signage.
Common Briefs
What Custom Offices Get Built For
Site administration offices, first-aid and induction rooms, training rooms and classrooms, and sales offices finished in corporate colours: every configuration is quoted per project against the documented floor plan.
Construction & Infrastructure
Site administration offices, induction rooms and first-aid rooms designed to the project's floor plan and compliance overlay.
Mining & Resources
Mine-spec builds on purpose-built new High Cube shells: PIR fire-rated lining, mine-spec electrical, engineered rather than retrofitted.
Oil, Gas & Energy
Training rooms, classrooms and specialist workspace briefs engineered on the same three ISO 668 platforms.
Military & Defence
Engineered-to-brief workspace builds for defence and government sites, from secure offices to training rooms.
Send your floor plan, headcount and fitout requirements and an SCS engineer prices the build.

Documentation with your quote
No configurator, no price list. Most container site office manufacturers in the search results are resellers quoting someone else's factory. SCS is the factory: describe the job and an SCS engineer comes back with a buildable specification, production drawings for sign-off, and a factory-direct quote. The tables on this page carry the current option set; the full specification and drawing set arrives with your quote.

Frequently Asked Questions
The questions buyers ask most often about custom container office builds.
Can you add a toilet to a container office?
Yes. Toilets, washbasins, showers and full ensuites are factory-installed wet-area options. The build runs supply and waste through the floor, wet-area flooring is waterproof with waste outlets, and Australian deployments are plumbed to AS/NZS 3500. Wet areas are positioned on the floor plan at the design stage.
What insulation options are available for container offices?
SCS fits 50mm EPS wall and ceiling panels as standard, and 50mm fire-rated PIR on high-compliance and mine-spec builds. Across the category, EPS is the cost-effective option, PUR the higher-spec step and PIR the fire-performance-rated system. Climate and compliance requirements drive the choice.
What is a flat pack container office?
A flat pack container office is manufactured as folding panels rather than a rigid welded unit, so several offices ship in the freight volume one assembled unit occupies. Panels are assembled into a finished office on site. The format suits multi-unit orders and routes where freight cost outweighs assembly time. An expandable container office folds out on site into floor space larger than its shipped envelope, and a foldable container office packs back down for redeployment between projects.
Can container offices be joined together?
Yes. Joining kits connect units into wider layouts, and joining two 40ft units yields around 50 m² of connected floor space. Two 10ft units ship coupled as a single CSC-plated 20ft High Cube and separate on site. For larger compounds, SCS builds multi-unit office complexes as engineered assemblies.
Are custom office electrical fitouts compliant with AS/NZS 3000?
Yes. AS/NZS 3000 is the baseline electrical specification on every custom site office: switchboard, RCD protection, GPO outlets and LED lighting, with three-phase circuits where the load calls for them. Mine-spec builds step up to full Australian Standard mine-spec electrical, adding smoke alarms, exit lighting and illuminated safety signage.
