CNMC 40FT Dual-Wing Expandable Container House – Full-Size Modular Facility for Large-Scale Camps, Field Operations & Multi-Zone Accommodation
The 40FT Dual-Wing Expandable Container House is the largest deployable unit in the CNMCH folding modular range. It is not simply a scaled-up version of the 20FT model — it is a purpose-built structure designed for projects that require room-by-room separation, dedicated functional zones, and the capacity to house more people under a single roof. When folded for transport, the unit measures 11.8 meters long by 2.2 meters wide, fitting within standard 40-foot container dimensions and shipping on a single flatbed without oversize permits. When both wings are deployed, the interior expands to 11.8 meters by 6.2 meters, delivering approximately 74 square meters of usable floor area — equivalent to a two-bedroom apartment with a separate living room, kitchen, and bathroom.
The expanded floor plan is large enough to be divided into three distinct bedrooms, a combined office-and-meeting-room layout, or a fully equipped medical suite with a waiting area, consultation room, and treatment bay. The structural frame is a hot-dip galvanized Q235B steel assembly with a 2.5-millimeter minimum wall thickness, clad in 75-millimeter insulated sandwich panels with rock wool or EPS cores. The unit is pre-wired, pre-plumbed to customer specification, and finished at the factory with interior wall panels, ceiling, and flooring. On-site deployment requires a level surface, a crew of four, and about one hour to expand and lock the structure.

74 Square Meters of Column-Free Interior Space
The expanded interior of the 40FT unit provides 74 square meters of usable floor area with no internal load-bearing columns. This uninterrupted span allows the space to be subdivided in any configuration the user requires. The most common layout divides the area into three private bedrooms and a central common area, or a large open-plan office with a separate meeting room and kitchenette. The absence of columns means that partition walls can be repositioned in the future if the use case changes, without structural modification.
Single-Unit Delivery, Multi-Room Capability
Where a 20FT unit can function as a single room or a two-room layout, the 40FT unit can deliver three or four separate rooms from a single delivered structure. This eliminates the need to purchase, transport, deploy, and interconnect multiple smaller units to achieve the same capacity. For a camp requiring 12 separate rooms, for example, four 40FT units will suffice where six 20FT units would be needed — reducing transport volume, foundation work, and inter-unit connection time by one-third.
Designed for Repeated Folding Cycles Over 15+ Years
The hinge and locking mechanism is the most critical component of any folding structure. The 40FT unit uses heavy-duty galvanized steel hinges with a bearing surface area sized to distribute the weight of the extended wings across the full height of the frame. The locking pins are machined from heat-treated alloy steel and engage with hardened steel receiving sockets. The manufacturer rates the mechanism for more than 500 expansion cycles, which corresponds to a service life of 15 to 20 years under normal project rotation schedules.
Pre-Insulated and Sealed for All-Weather Performance
The wall panels use a sandwich construction with a 75-millimeter core of rock wool or EPS foam, achieving a thermal transmittance value of approximately 0.45 W/m²K. The roof panels are similarly insulated, and the floor assembly includes a 15-millimeter cement-fiber board base topped with 2-millimeter PVC flooring. All panel joints are sealed with EPDM gaskets, and the roof is designed with a slight slope for drainage. The double-glazed sliding windows use thermal-break aluminum frames. This envelope keeps the interior comfortable across ambient temperatures from -20°C to 45°C without excessive HVAC load.
Factory-Installed Electrical and Plumbing Systems
The electrical system is fully installed at the factory, including the distribution board, circuit breakers, wiring, LED lighting, switches, and power outlets. The system can be configured to meet the electrical standards of the destination country — 110V or 220V, 50Hz or 60Hz, with socket types matching local requirements. Optional plumbing installations include a complete bathroom with toilet, shower, washbasin, and water heater, as well as a kitchen sink with hot and cold supply. All pipework is pressure-tested before the unit leaves the factory.

Large Construction Site Headquarters & Project Office
Major civil engineering projects — dams, bridges, tunnels, railways, and power plants — require a substantial on-site management facility that can accommodate multiple departments. The 40FT unit provides space for a project manager’s office, engineering desks, a quantity surveyor’s station, a meeting room, and a document archive, all under one roof. When the project progresses to a new section, the entire office folds and moves with the management team.
Mining Camp Accommodation for 6 to 8 Personnel
In remote mining operations where fly-in-fly-out crews work on rotating schedules, the 40FT unit serves as a self-contained accommodation module for six to eight people. The interior is divided into three bedrooms with bunk beds, a shared living area with a dining table and television, and a kitchenette. An attached bathroom module provides showers and toilets. Multiple units are arranged in rows to form a camp that can house 50 to 100 workers within days of delivery.
Field Hospital & Medical Treatment Center
Healthcare organizations operating in remote or post-disaster settings use the 40FT unit as a deployable medical facility. The expanded floor plan accommodates a triage and waiting area, two consultation rooms, a treatment bay with an examination bed, a pharmacy counter, and a staff rest area. The pre-installed electrical system supports medical lighting, refrigeration for vaccines, and charging for diagnostic equipment. The sealed, cleanable interior surfaces meet basic infection control standards.
Military Barracks & Tactical Operations Center
Defense forces use the 40FT unit as a squad barracks, company headquarters, or communications center. The large interior allows for a command-and-control setup with map tables, radio equipment, and multiple workstations. The steel construction provides a base level of ballistic protection, and the unit can be upgraded with armor panels for deployment in higher-threat environments. The folded transport profile allows multiple units to be airlifted or convoyed to forward operating locations.
Refugee Camp Housing for Extended Families
Humanitarian organizations responding to displacement crises deploy the 40FT unit as family shelter for six to ten people. The interior is partitioned into two or three sleeping areas, a communal living space, and a storage area for personal belongings. The lockable steel door and window shutters provide security, and the insulated construction keeps the interior temperature stable in hot and cold climates. Multiple units can be arranged in a planned layout to form a dignified camp environment.
