Going through a process of investigating symbiotic relationships in nature and in the social environment, I was interested in the moment that the equilibrium between the organisms is lost and the mutualistic relationship becomes parasitic. In architectural terms I aim to find the symbiotic moment where the flow of natural resources create an autonomous self sustained living organism being supported by an ecological system. The Andre Bloc Museum coexists with the historic elements of the site creating a commensalism relationship with the host. However, it can be considered as parasitism due to its physical presence and the way it takes over the site. The relationship of the museum with the broader site generates a symbiotic relationship through an exchange of resources where the surrounding community contributes to the biomass procedure and in exchange provides them with surplus energy. The relationship of the user with the site acts as a parasite but with the museum they have a mutualistic beneficial relationship. An expanded biological growth is supported by a technological parasitic skin sustaining the nature, but over time gains dominance of the site. In nature the relationship between different elements can be much more clearly defined whereas in architecture the relationships are much more complex since there are more elements at play. The architectural practice contributes beneficially to the urban context and the user. However it can have parasitical qualities to the existing physical and environmental context of the site when sustainability is pursued. When the equilibrium is lost between form and self-sufficiency it can be a downside evidence of the constructed world being transformed into a place of exaggerated control.
