Croatia Hybrid Steel Residence
1 / 11
About this project
Located in Croatia, this striking 202 m², 2.5-story residence demonstrates the advanced engineering capabilities of TheoSteel's hybrid construction systems. The complex A-frame geometry required a sophisticated structural approach, pairing a primary skeleton of heavy structural steel for immense load-bearing capacity with a secondary framework of cold-formed light gauge steel (LGS). This integration ensures exceptional seismic stability, high wind resistance, and optimal acoustic and thermal insulation across all levels.
Through comprehensive BIM-driven digital modeling, the intricate connection points between heavy and light steel elements were pre-engineered with millimetric accuracy. This industrialized off-site pre-fabrication allowed for rapid, waste-free assembly on-site, delivering a highly durable, energy-efficient, and architecturally distinctive home engineered for long-term climate resilience.
