Paradoxically, the architecture in the Tropics is a mountain of absent evidence, ideas without a manifesto, conversations without a text, experiences without a record. It comes from an obsession with identity, present everywhere but frequently ignored. The manifesto is the sum of different interpretations of the past related to a diffuse prensent. It aims to give an idea about what tropical space is, its possible origins, and consequences, to built a definition, a restructured gaze on the architecture with a tropical thought establishes intermediate conditions, wich do not attend to the dichotomy or dualisms. It is a thought that accepts contradiction and ambiguity, as a space, as an attitude: Specific Ambiguity as a double way of thinking and creating an ambivalent, complex and contradictory, imprecise, mestizo, and multi-referential architecture. This concept is exemplified throught a selection of works by AGENda, most of them located in Medellin and Mexico.
