What kind of common ground can the Smooth and the Striated have with architecture? It is question that has certainly been posed repeatedly, but which each time slips out of any fixed or absolute answer. These concepts, as developed by Gilles Deleuze and FĂ©lix Guattari, are available as valuable tools for understanding the philosophy of space, and consequently for recognizing and reading into architectural qualities and design decisions. Through the following study, a spatial exploration of three examples will attempted, looking for the striating factors, the dynamics they introduce, but also the possibility of returning to the smooth condition allowed to the spatialities they create. Mies Van Der Rohe's Barcelona Pavilion, UNStudio's Theater of Immanence and Herzog & de Meuron's Museu Blau are selected as a ground for a comparative process, which aims to identify common elements in different aspects, and the corresponding results that occur. The logic used in each example for the processing of matter, spatial organization and mental connections, are factors that can potentially enrich, or otherwise burden a space, over-defining its identity. Through the convention that the perceived freedom of mental and physical voyage in space is a token of the smooth, this analysis intends to identify the striating factors as more or less tight, seeking answers to the introductory question.
