Modular House

Modular，Prefab，Reuseable

28 sqm Butterfly Container House

Expandable tiny homes are prefabricated modular buildings with galvanized steel frames and composite sandwich panels. Their defining feature is two outward-extendable side “wings”: folded into standard shipping-container size for cost-efficient ocean/land transport, they expand on-site to double or triple the usable area.
Installation takes just hours to one day with minimal labor, as utilities like water and electricity are pre-fitted in factories. Boasting waterproof, fire-resistant, and thermal-insulated properties, they suit diverse climates and uses—from ADUs, vacation homes, and private home，farm house etc.

Compared with fixed container houses or prefabricated cabins, they offer superior space flexibility, faster deployment, and lower logistics costs, making them a budget-friendly alternative to traditional housing.

Process for Installation

To install, first level the site, hoist the folded unit into position, remove transport locks, then slowly extend and lock both wings. Adjust and secure the support legs, reinforce the connecting hinges, hook up pre-installed utilities, and check structural stability before use—all taking just hours. Key precautions include keeping the unit strictly level during setup, operating wing extension steadily to prevent hinge damage, anchoring the base with expansion bolts in windy areas or for long-term use, and following manufacturer guidance for first-time installation to ensure safety and durability.

Key Features

Space Flexibility

Folds into standard shipping container size for easy storage; expands outward on both sides to double or triple the usable area, balancing transport compactness and on-site spaciousness.

Cost-Effective

LogisticsFits standard sea/land freight specifications. Multiple units can be loaded into one container, slashing long-haul shipping costs—ideal for export markets like Australia and the Americas.

Rapid Installation

Can be fully set up in hours to one day with minimal labor. Pre-installed water, electricity, kitchens and bathrooms enable immediate use upon on-site connection.

Durable & Climate-Resistant

Galvanized steel frame paired with rock wool/polyurethane sandwich panels delivers waterproof, fireproof, thermal-insulated, windproof and earthquake-resistant performance for diverse climates.

Modular Scalability

Supports horizontal/vertical assembly to form multi-unit complexes, suitable for resorts, construction dorms, disaster shelters and other scenarios.
