‘MycoLoofah’: Operating within the discourse of biodigital design, the project addresses contemporary built environment challenges of material resources and low urban biodiversity. Western-centric obsessions with permeance and sterility have favoured the development of material composites that are resistant to ageing, decay or biological growth through the use of chemical or synthetic agents. These materials are unable to be reused or recycled and with the average lifespan of buildings in decline, mostly end up in landfill. In line with these ecological and material insecurities, the project explores the use of hybrid living materials as low-energy, rapidly renewable building materials. Hybrid composite materials are ‘grown’ together comprising mycelium, loofah and grass roots, proposing a more biological, non-permanent architecture. These materials engage with circular material economies which can reduce the impact of architecture and construction on the climate. Yet they can also serve as bioreceptive substrates for the secondary growth of photosynthetic organisms that can contribute to carbon reduction and increase biodiversity in cities.
