Overview
Mine-spec portable accommodation, factory-direct
Mining housing is SCS Global's portable, factory-finished workforce accommodation built for mining camps, construction sites, defence forward bases, and remote project deployments. We manufacture these units (known as dongas in Australia, porta cabins internationally) factory-direct from our Yixing, Jiangsu facility in 20ft single-room and 40ft two-room footprints, with ensuite, kitchenette, mine-spec fitout, and Region D cyclone-rated variants. Every unit ships into our full mining camp accommodation range and meets AS/NZS 3000 electrical, AS/NZS 3500 plumbing, and NCC 2022 habitable building standards on AU and NZ deployments. The 20ft single-room suits FIFO occupants and supervisor sleep-in rooms. The 40ft two-room covers two-up rotations and project-office combinations. Both come off the same line, against the same fitout baseline.
Specifications
Mining Camp Housing: Unit Specifications
Units come in two standard sizes: 20ft single-room at 6,058 x 2,438 x 2,591 mm and 40ft two-room at 12,192 x 2,438 x 2,591 mm. Base dimensions follow ISO 668:2020 Series 1 freight containers so each unit transports under standard container handling, road permits, and stacking rules. Custom dimensions and non-standard layouts are built to project brief.

Configurations
Mining Donga Sizes and Layout Options
The 20ft single-room is the standard FIFO sleeping unit: bed, desk, wardrobe, split-system A/C, and full electrical fitout. A bunk-bed variant covers higher-density use on exploration teams, shutdown crews, and defence forward bases. The 40ft two-room splits into two private rooms with a factory-installed partition, each with its own door, window, and bed. It suits supervisor pairings, two-up rotations, and sleep-plus-office combinations. Custom layouts including three-bed bunk-share and meeting-room hybrids are built to project drawings.
Ensuite
Ensuite Option
The ensuite variant adds a private shower, toilet, and vanity (plumbed to AS/NZS 3500 on AU/NZ jobs) to either the 20ft or 40ft footprint. The fitout includes exhaust ventilation, a hot-water service, and labelled external water and waste connections. This is the highest-tender-frequency configuration on AU mining-camp procurement. Tier-1 operators write it into camp specifications by default, particularly for supervisor and long-stay rotational rooms where a shared ablution block would force a walk across the camp grid in the wet season.
Compliance
Compliance and Cyclone Rating
Every unit complies with AS/NZS 3000:2018 (electrical wiring rules), AS/NZS 3500 (plumbing and drainage, ensuite/kitchenette variants), and NCC 2022 habitable building requirements. Cyclone-rated variants are engineered to AS/NZS 1170.2 Region D and AS 4055 for Pilbara, Kimberley, North Queensland, and NT-coast deployments, with verified tie-down spec and engineering certificate supplied at delivery. A cyclone-rated unit ships with the engineering certificate, the tie-down detail, and a Certificate of Compliance covering the electrical, plumbing, and structural scope.

Configuration Options
Portable Dongas: Mine-Spec Fitout Options
Mine-spec fitout means turnkey accommodation delivered ready for FIFO deployment. The standard option set covers the items below. Every option is built on the same Yixing line as the base unit. Factory-direct means the fitout decisions sit inside one production sequence rather than getting bolted on after the box leaves the manufacturer.
Kitchenette
Factory-fitted cooktop, sink, bench, and overhead storage for supervisor or long-stay deployments.
Security Upgrades
Upgraded door, window security mesh, and lock specification for remote or high-value sites.
Solar-Ready Electrical
Pre-wired for off-grid PV integration with DC isolator and inverter mount provision.
Fire-Rated Linings
Fire-rated linings and door upgrades for higher-risk service environments.
Custom Dimensions and Colours
Non-standard layouts built to project drawings. Factory-painted exterior in custom colours.
Applications
Applications and Deployment
Mining housing units are the workhorse of remote workforce accommodation. Mining majors, tier-1 contractors, and EPC companies deploy them across iron-ore, copper, gold, and bauxite operations. They also serve oil and gas camps, construction laydowns, and defence forward-operating bases.
Mining & Resources
FIFO sleeping units for iron-ore, copper, gold, and bauxite operations. Single-room and twin-share configurations deployed across Pilbara, Kimberley, North Queensland, and West Africa.
Oil, Gas & Energy
Rotational accommodation for pipeline projects, oilfield camps, and LNG construction sites. Ensuite and kitchenette variants for long-stay supervisory and engineering crews.
Construction & Infrastructure
BoP and Tier 1 construction laydowns. Workforce accommodation for civil works, shutdown campaigns, and infrastructure projects where no permanent housing exists.
Military & Defence
Forward operating bases, emergency-services deployments, and contractor accommodation. Cyclone-rated and security-upgraded variants for high-exposure sites.

Frequently Asked Questions
Four questions procurement, operations, and engineering ask most often about mining housing units.
What is a donga?
A donga is a portable, self-contained accommodation unit used at mining camps, construction sites, defence forward bases, and remote project locations across Australia and New Zealand. The units are factory-finished, relocatable, and form the sleeping module of a modular workforce camp. International equivalents are porta cabin (Middle East, India) and demountable (UK and parts of AU/NZ).
What is a donga house?
A donga house is a semi-permanent residential application of the same prefabricated module used on mining camps: a steel-framed, panel-built unit with full electrical and plumbing fitout, occupied as housing rather than as rotational workforce accommodation. The mine-spec build, by contrast, is engineered for transport, relocation between sites, and quick connection to temporary camp services.
What is donga accommodation?
Donga accommodation is portable workforce housing deployed at mining camps, construction sites, and remote project locations where no permanent housing exists. Donga mining accommodation is the most common application: a factory-fitted sleeping module with bed, A/C, and full electrical, sized in 20ft and 40ft footprints, combined with ablution, kitchen, and recreation modules to form the full camp.
How much does a donga cost?
Pricing depends on size (20ft vs 40ft), single-room vs multi-room, ensuite or kitchenette inclusion, cyclone rating (Region A/B/C/D), fire rating, and unit count. Custom fitout, paint colours, and solar-ready electrical also move the number. Factory-direct from Yixing strips reseller margin.
