A Review of Mycelium-Based Composites in Architectural and Design Applications

Abstract

Mycelium-based composites are a promising sustainable material with inherent fire resistance and acoustic absorption properties, the extent of which depends on the fungal species, the substrate, and the growth technology. These materials exhibit superior fire performance compared to synthetic polymers, characterized by low heat release, minimal smoke production, and a high char yield that inhibits flame spread. Some composites have even demonstrated self-extinguishing capabilities. Despite these advantageous properties, their application in the construction industry remains limited. To assess mycelium’s current trajectory, this study analyzes 90 real-world architectural and design projects. Our findings indicate that Ganoderma lucidum and Pleurotus ostreatus are the most commonly used fungi, cultivated on substrates such as straw, wood, and sawdust. Architectural applications are dominated by building blocks, insulation, and facade panels, whereas design and art applications focus on packaging, furniture, and sculptures. A key distinction emerges: architectural projects prioritize function, while artistic projects emphasize esthetic experimentation. Although commercially successful in packaging, the use of mycelium in construction is currently limited to temporary structures. Enhancing its structural and load-bearing properties through further research is essential for its widespread use in architecture. However, mycelium is poised to become a key material that drives innovation in sustainable construction.
