Chile's latest architectural innovation, the Industrialized Building System Prototype II (IBSP II), has been unveiled, showcasing a modular housing design elevated on stilts to adapt to difficult terrains. This development is a collaboration between architects Ignacio Rojas Hirigoyen and Leonardo Gúzman Valencia, aiming to provide flexible housing solutions amidst a global housing crisis.
What Happened
The IBSP II project, completed in 2025, builds upon insights gained from its predecessor, the first prototype introduced in 2023. Located on a steep 5,000 square meter site in Matanzas, Chile, this 120-square-meter modular home utilizes a lightweight, self-supporting stilt system. These diagonal, triangular supports allow the structure to rise above the ground, effectively dealing with the site's challenging topography. This innovative design separates the framework from the enclosure, enabling the housing envelope to play an active role in climate mediation rather than merely serving as a boundary.
Why It Matters for the AECM Industry
The IBSP II prototype represents a significant leap in addressing the growing demand for adaptable and sustainable housing solutions. Its modular and elevated design mitigates the environmental impact on sensitive terrains, offering a model for future construction in similarly challenging environments. For the AECM industry, this approach not only reduces ground disturbance but also enhances the flexibility and resilience of residential structures against climate variability. The project underscores the potential for modular construction to address housing shortages while maintaining environmental integrity.
What's Next
As the global housing crisis persists, the principles demonstrated by the IBSP II could influence future architectural practices, particularly in regions with challenging landscapes. Industry professionals should watch for further developments in modular construction techniques and the potential for wider application of elevated housing solutions in diverse geographies. This project may pave the way for policy changes and new building codes that facilitate innovative construction methods.
