A newly achieved perception of spatiality and the definition of a discourse around means of architectural signs will be the topic of a conversation between the art critic Emiliano Gandolfi and the architect Kersten Geers. The appearance of space is unconceivable without a dissertation on time. Architecture is not necessarily a temporal experience, but time, through its evolutionary cultural process, defines what we should consider beautiful at a given moment. Within Robert Schumann’s poetic beauty, based on humans’ conscious and creative intervention in the nature, and the Japanese definition of wabi-sabi that sees beauty as imperfect, impermanent, and incomplete, our perception flows, in various constructions of signs, through space. Emiliano Gandolfi is an architect and curator of the Netherlands Architecture Institute in Rotterdam, where he developed several exhibitions and public events such as Newer Orleans, DynamiCity – Tactics for a Changing Metropolis, and Spectacular City – Photographing the Future.
