Expandable Modular Home: Rapid-Deploy Living Solutions
Modern construction demands speed, efficiency, and flexibility. The Expandable Modular Home from WECHEER Holding Group delivers all three through innovative twin-wing engineering. With over 40 years of experience in modular building, WECHEER has six smart manufacturing facilities that produce more than 200,000 units each year, giving them an annual production capacity of more than 300,000 units.They are changing the way you think about both temporary and permanent homes.
Their expandable units come in different sizes, from a spacious 76m² (40ft flat-top) to a smaller 27.5m² (20ft narrow).
The unique 700mm folding design helps cut shipping costs by 60% because six units can fit into one 40HQ container.To make sure comfort in any environment, they include electrical systems, high-performance insulated panels made from EPS, rock wool, or PU, and strong galvanized Q235B steel frames.
What Makes Our Expandable Modular Home Different?
The product solves the industry's toughest challenge: the logistics-volume ratio. Traditional modular units waste container space and inflate shipping costs. Our unique butterfly mechanism folds the structure to double or treble the living area on-site after compacting it to the size of a typical shipping container.
The galvanized steel frame can handle earthquakes up to level 8 and winds up to level 11, which is about 120 km/h.Compared to regular temporary homes, the high-density sandwich panels offer insulation that is between R-12 and R-20.Based on the material inside the panels, the fire safety meets either Class B1 or A1 standards.
Each unit comes with all the wiring already installed, including switches, LED lights, outlets, and a circuit breaker panel.The UPVC double-glazed windows and 3mm anti-slip PVC floor ensure both long-lasting durability and a comfortable living space from the beginning.
