To continue the exponential expansion of the past is no longer reasonable, responsible, or feasible. Terra incognita is a memory. Post-Industrial Latent Space presents it's counterpoint: the urbis incognita--hidden, forgotten, and ignored 'wilderness' of the city inviting exploration and temporary in habitation. It is present in the hidden, forgotten, illegal, appropriated, and ignored contextual spaces we see every day. This new frontier sits quietly waiting to be explored and experienced. These post-industrial latent spaces permeate the contemporary built environment and present an evolving opportunity for architecture. They exhibit architectural dreams and fears, at once inspiring architecture's promise and aware of its ultimate entropy. Here the lines between solid/void, building/landscape, inside/outside become ambiguous yet, paradoxically present. In Post-Industrial Latent Spaces we see buildings long after the builders have left, the layers of human detritus peel away and materials and structures begin a temporal existence abstracted by time.
