GRAND JUNCTION, Colo. — A team of researchers based in Montana has unveiled a potentially transformative innovation in sustainable construction: a building material made from fungi and bacteria that could one day lead to “living” homes capable of self-repair and environmental harmony.
According to a new study published in Cell Reports Physical Science, scientists have developed a living, root-like framework mimicking the natural networks fungi form beneath the soil. This foundational structure—based on mycelium, the vegetative part of fungi—could serve as the building block for regenerative architecture, offering a cleaner, greener alternative to traditional construction materials like concrete and steel.
“It could be possible to live in homes that are created out of fungi and bacteria,” said Chelsea Heveran, lead author of the study and professor at Montana State University.
From Spore to Structure: The Science Behind It
The key to the innovation lies in mycelial networks, which not only grow rapidly but also form dense, fibrous matrices strong enough to support physical structures. The research team succeeded in designing a prototype framework that could grow itself into form, with the added ability to self-heal minor cracks or damage.
Though still in the early stages, the potential applications are vast:
-
Biodegradable housing materials
-
Low-carbon construction
-
Buildings that repair themselves over time
-
Temporary shelters grown on-site
-
Adaptable, compostable architecture
Heveran emphasized that while the breakthrough is significant, it is still far from commercial deployment.
“This is just a first step in the process,” she said. “It will take much more work before this becomes a real possibility.”
Why Fungus?
Cement, which accounts for roughly 8% of global CO₂ emissions, has become a major target in sustainability efforts. The fungi-based alternative is not only low-emission, but it could also be grown with minimal energy inputs and decomposed safely at the end of its lifecycle—two features that radically contrast with current construction materials.
Additionally, fungi are naturally resistant to fire, water, and pests—a trifecta of resilience that’s gaining traction in experimental architecture circles worldwide.
Mycelium in Practice: A Growing Global Interest
While the Montana project is groundbreaking in its structural ambitions, mycelium has already been tested in other areas of design:
| Application | Description |
|---|---|
| Insulation panels | Tested by firms like Ecovative and Biohm |
| Packaging materials | Used as an alternative to Styrofoam |
| Furniture | Designers use molded mycelium for biodegradable decor |
| Art installations | Grown forms have been used in temporary architecture |
Companies in the U.S., U.K., and the Netherlands are actively exploring how to upscale mycelium technologies, with some governments offering grants and subsidies for bio-based materials research.
Challenges Ahead
Despite the buzz, several obstacles remain:
-
Scaling growth to industrial levels is still a technical hurdle.
-
Durability and building code compliance are uncertain.
-
Moisture control and longevity in variable climates require more testing.
Still, the idea of mushroom-based homes is no longer science fiction. With advances in synthetic biology, regenerative materials, and climate-focused architecture, the age of “living buildings” may be just around the corner.
“We’re not growing houses tomorrow,” Heveran said, “but we are laying the foundation for a very different future in construction.”
