Kizuki has completed Japan’s first government approved two-story 3D printed reinforced concrete house. The project meets Japan’s stringent seismic design requirements and demonstrates that 3D printed reinforced concrete can be applied as a structural alternative to timber construction in one of the world’s most earthquake-prone regions.
- First government approved two-story 3D printed reinforced concrete house in Japan
- Full seismic compliance confirmed under national building standards
- Total printed area of 50 m² (537 sq.ft.) across two floors using 39 m³ (1,371 cu.ft.) of material
- Cave-inspired architecture featuring 3D printed arches, floor slab, and roof slab
- Four-person crew operating the printer under seasonal conditions ranging from below 10 °C (50 °F) to 35 °C (95 °F)
- Custom printer configuration enabling printing from 0,5 m (20 in) below ground to a total height of 7 m (23 ft)
The 50 m² (537 sq.ft.) house consists of a 31 m² (329 sq.ft.) ground floor and a 19 m² (209 sq.ft.) upper floor. The design follows a cave-inspired architectural concept, incorporating 3D printed arches, a 3D printed floor slab, and a 3D printed roof slab. Several interior elements were produced using 3D printing to extend the curved geometry throughout the interior.
