Spanish (Rotterdam based) architects Helena Casanova and Jesus Hernandez have developed a strong pictorial strategy for their exhibition in the Architektur Galerie Berlin (17.05. - 29.06.2013). The book Scale & Perception with the same title as the exhibition serves to provide greater insight to Casanova + Hernandez' central theme of architecture, based on photographs by Christian Richters. They show, from his point of view, the many overlapping layers which define the visual perception of the buildings. They are accompanied by numerous plans and sketches showing the role of every single layer in the creation of the overall perception. The book is completed by the manifesto-like text "Scale & Perception: Rethinking Phenomenological Architecture in the Global Age" by Casanova + Hernandez.
