Today's sustainability in architecture takes into consideration the complete life cycle of buildings and their components, from resource harvesting and material production to recycling. In recent years, the concept of living architecture has emerged and seeks to integrate principles of life to architecture to reduce resource consumption. The principle of biological growth has architectural potential such as: adaptation, resilience, dynamics, differentiation and continuous functionality. In order to optimize the building process, the principle of growth can be applied to different building stages, from material production and building construction to operation and maintenance. In this regard, biomimetics and biotechnology serve as methods of transferring biology to architecture by abstracting and using principles in artificial systems, and by integrating living organisms into the design and production process. This paper presents existing projects that use biological organisms in various stages of material production, building construction, operation and maintenance. A case study on myceliated material, where fungal mycelium is grown on agricultural waste, was carried out and provides an explanation of this process and its potential. Mycelium functions as a connecting network, solidifying otherwise amorphous substrate. Panels targeting diverse architectural functions can be made from myceliated panels by changing growth conditions and post-growth treatments. This case study focused on scaling the mycelium growth process up from laboratory scale to large panels that were implemented in an outdoor environment as a prototypical facade. In conclusion, despite the lack of actual growth in today's buildings, growth using biological organisms is well-discussed and an expanding field. The case study showcases the potential of implementing biological organisms in facade prototypes to serve in material production and building operation stages. These research projects bring the integration of biological systems in architecture one step closer to changing current practices in the building industry.


Numerous architects and research groups discuss the concept of living architecture and seek to integrate principles of life to architecture in order to reduce resource consumption (Beesley, Hastings, and Bonnemaison
