Big Living, Two Stories
The CHOMEX Grand Duo 40′ + 20′ Two-Story Expandable Container Home brings full-size living to a compact modular footprint with approximately 1,250 SF of enclosed space across two levels, plus a spacious rooftop terrace.
The first floor features the home’s main living areas, including an open living and dining space, kitchen, bedrooms, bathroom, and interior staircase. The second floor adds additional private living space with bedrooms and a full bathroom, while the remaining roof area becomes a large outdoor terrace.
Designed for families, vacation properties, Airbnb investments, guest accommodations, or sites where maximizing usable space is essential, the Grand Duo combines the efficiency of CHOMEX expandable construction with the space and separation of a conventional two-story home.
