The building is a research institute for studying mycoremediation: the process of remediating contaminated soils and groundwater through strategic use of fungus species. This project proposes an architecture formed from the integration of a mycoremediation to mycelium ecology which is achieved through a series of expressive and bio-integrated mycelium skins. These skins make use of off-site computational manufacture and constructional replacement strategies. Computational and physical research into fungal growth logics and mycelium construction is embedded within the skins. The environmental control systems and the peripheral ornamentation of the skins is here used as an approach to transparent architectural cybernetics.
