No less striking, though less colorful, the Departmental building by Estudio Carme Pinós plays with rigid geometries. Windows and casements in gray metal flow in a zig-zag pattern over white walls. These patterned volumes alternate with solid gray orthogonal sections, all joined by a curved central form. Stepped and circular cut-out shapes are used throughout the interior, demonstrating some of Pinós trademark attention to quirky details. To help maintain internal temperatures, window shutters open and close automatically according to solar conditions.
