Stackable container houses leverage intermodal shipping container architecture for vertical expansion. Our engineered stacking systems use patented twist-lock mechanisms that allow secure connections up to eight units high. Structural modifications include reinforced corner posts and load-bearing walls to handle dynamic loads. Stacked configurations require careful planning of vertical circulation (stairs or external walkways) and utility distribution through centralized chases. Acoustic insulation between floors utilizes resilient channels and sound-absorbing underlayments. Wind and seismic bracing systems ensure stability for multi-story arrangements. We offer pre-designed stacked complexes including duplex homes, apartment buildings, and mixed-use developments. All stacked units undergo finite element analysis to verify load distribution, with optional third-party engineering certification.
