In Japan, a country exposed to earthquakes, typhoons, and floods, the company TCL Co. has developed the Ezdome, a modular house in the shape of a geodesic dome that can be assembled in less than two hours.
Its design aims to offer a dignified and safe shelter for families affected by natural disasters, avoiding the saturation of collective shelters.
Design and Structure
The Ezdome is characterized by its spherical shape, constructed from a network of triangles and polygons that ensure lightness and strength.
- Wind resistance: the geometry reduces the pressure of intense gusts.
- Snow resistance: the panels withstand accumulations in extreme climates.
- Dimensions: 3.36 m exterior diameter, 2.55 m total height, and a weight of 300 kg.
- Interior space: 3.28 m diameter and 2.35 m height, sufficient for a small family.
The assembly includes 38 interlocking panels and a lighting dome. Two adults can assemble it in 60 to 90 minutes, without the need for specialized tools.
Materials and Habitability
- Walls and floors: made with high-density polyethylene (HDPE).
- Roof: incorporates transparent polycarbonate for natural light entry.
- Absence of pillars and beams: reduces risks during tremors.
- Field tests: withstands temperatures up to -8 °C, ensuring comfort in winter and summer.
The housing is not disposable: it is reusable and durable, with an approximate cost of 1.32 million yen (7,192 euros), making it a competitive option compared to other prefabricated alternatives.
Uses and Advantages of Modular Houses
In addition to its function in emergencies, the Ezdome can be used as:
- Temporary accommodation in gardens or events.
- Volunteer camps and outdoor festivals.
- Logistical coordination centers in civil protection.
One of its main advantages is the creation of an independent microspace, which preserves privacy and reduces stress in evacuation situations.
Real Experiences and Future Projection
During the Noto Peninsula earthquake, modular homes provided shelter to displaced families. They have also been used in recent emergencies in Turkey, Syria, and Morocco, demonstrating their effectiveness in international contexts.
These models could be adapted to rural areas or areas exposed to forest fires, flash floods, and preventive evacuations. Their quick installation and portability make them a valuable tool for civil protection devices, avoiding dependence on large collective tents or permanent infrastructures.
The Ezdome represents a Japanese innovation in modular architecture, capable of offering safety, privacy, and comfort in critical situations. Its geodesic design, resistant materials, and quick assembly make it a versatile solution to the challenges of a world increasingly exposed to natural disasters.
