Architecture and design studio Cutwork developed a concept called the Cortex Shelter as a solution for rapidly putting together refugee shelters. The structures rely on metal tubes to form a frame, plus the use of Cortex Composites, a type of flatpack concrete sheeting that can be rolled into place and set into a form with the addition of water. The shell hardens in 24 hours and has the potential to last for decades if maintained. Notably, Cortex Composite is said to be two times stronger than traditional concrete.
The finished structures have high windows as a source of light, as well as ample space for a kitchen, bathroom and even options for solar panels to be added to the roof to generate power.
