German students grow igloos from mushrooms for sustainable shelter

A team of architecture students at Frankfurt University of Applied Sciences (Frankfurt UAS) in Germany has developed MyGlu, a sustainable, mushroom-based igloo designed for hot, dry climates. The dome-shaped prototype is constructed entirely from mycelium—the root-like structure of fungi—grown on wood waste. This lightweight, modular, and fully biodegradable structure offers natural insulation, water resistance, and sound-dampening properties, making it suitable for climate-affected regions, humanitarian crises, or areas with material shortages. The design draws inspiration from traditional Arctic igloos but is specifically tailored to provide cooling and shelter in arid environments. The project, led by Florian Mähl, PhD, aims to establish mycelium-based construction as a key research focus at Frankfurt UAS, with plans to improve production processes and expand applied studies. MyGlu demonstrated promising thermal and acoustic performance during testing, showing potential as a low-cost, climate-neutral housing solution. Recognized with the university’s Sustain Award in
