MyGlu: Student-Built Mycelium 'Igloo' That Could Transform Affordable, Low‑Carbon Housing

Students build MyGlu: a mycelium dome for hot climates

A team from Frankfurt University of Applied Sciences has developed MyGlu, an igloo‑like dome made from mycelium — the root‑like network of fungi — that could offer a low‑cost, biodegradable alternative for shelter in hot, arid environments, according to Interesting Engineering.

Inspired by the hemispherical design of Arctic igloos, which trap air to retain heat, the students applied the same geometric principle in reverse: a dome can reduce heat gain and keep interior temperatures lower in extreme heat. The prototype was tested in laboratory and field settings and showed promising insulation performance and sound dampening.

Why mycelium?

Mycelium is naturally strong, lightweight, flexible, water resistant and fully biodegradable. It can be grown using low‑energy processes and agricultural waste, which can make it far less expensive and more climate‑friendly than many conventional building materials.

Potential uses and next steps

The project team — students and faculty — said they plan to expand research into mycelium‑based construction at Frankfurt UAS and with partners across academia. Designs like MyGlu could be especially useful for rapid, low‑cost shelters in humanitarian crises, refugee camps and post‑disaster situations where speed, cost and sustainability matter.

"MyGlu impressively demonstrates how cost‑effective and climate‑neutral construction can be achieved and opens up new avenues for research," said Susanne Rägle, vice president of research at Frankfurt UAS, per Interesting Engineering.

Industry and research groups are already exploring mycelium for a wide range of applications — from building blocks and small homes to furniture and packaging. The construction sector accounts for roughly 37% of global greenhouse gas emissions, according to the United Nations, and advocates argue that biomaterials like mycelium could help reduce that footprint if scaled responsibly.

While MyGlu is an encouraging prototype, researchers caution that further testing is needed on durability, weather resistance, hygiene, scalability and regulatory approval before mycelium structures can be deployed widely. Still, the project highlights a creative, low‑energy approach to designing the next generation of affordable, sustainable shelter.
