TECH_04 is an easy to assemble emergency shelter designed by Archi-tektura.eu with the guidance of Prof. Mick Eekhout and eng. Agata Jasiołek and constructed in collaboration with students from Wroclaw University of Science and Technology. The housing design was motivated by the need to provide improved living conditions for the refugees, homeless population and communities displaced due to natural disasters or conflicts.
Distributors / Implementing Organizations
Prefabricated components such as cardboard Sandwiches on the roof and walls. The floor is made of wood materials.
Intellectural Property Type

The shelter is made from pre-fabricated components on the floor, wall and roof. The independent elements are assembled to generate a 13 m2 of floor space for the comfort and needs of the intended occupants.
- The floor is made from 18mm thick impregnated OSB or plywood board with 15 layers of corrugated cardboard 7mm.
- The walls are made up of 8 layers of 7mm thick corrugated cardboard filled with 2 cardboards honeycomb panels 25mm thick and a 0.6mm aluminum layer. The walls have a vapor resistive layer on the inner walls and a waterproof layer on the outside to prevent damage to the cardboard.
- The door is made of a pinewood frame and two plywood boards each composed of a 20mm honeycomb cardboard panel.
- The roof is made up of panels that are interconnected to the walls and are made from cardboard honeycomb panels, and have a vapor barrier and a waterproofing layer on the inner and outer sides respectively.
According to the designers, the assembly can be done by non-technical professionals without any specialized equipment or tools for the work.
Components are prefabricated and can be shipped for replacement incase it is damaged.
1 to 5 years since it is meant to be an emergency shelter while temporary or permanent reconstruction solutions are being sought.
Manufacturer Specified Performance Parameters
EN-ISO 6946:2017 compliant U-values which provide a good thermal insulation. The wall has a thermal insulation capacity of 0.52 W/m2K while the roof and the floor have thermal insulation capacities of 0.54 W/m2K and 0.35 W/m2K respectively. The corrugated cardboard and honeycomb panels have a high insulation performance. The honeycomb panels should be at most 25mm thick to facilitate insulation through having the air pockets filled with air.
Vetted Performance Status
The shelter is under monitoring for the thermal performance, energy demand and intensiveness and structural durability by the Wroclaw University of Science and Technology designers and students involved in the project.
Easy to assemble requiring no professional skills or complicated tools. This guarantees the safety of the assembly process. Limited lifespan recommendation of up to 5 years to prevent collapse due to material deterioration from water or high humidity levels.
