The Bregenz-based practice of Bernardo Bader raised a wooden wing for a school in Lustenau, a town of the Dornbirn district, in northern Austria. The exterior surfaces of the window and door frames are painted red, visually connecting with the existing main building. Crowned with flat green roofs, the single-floor volume comprises functional units for three groups of children, 23 in each, which open out to the garden through courtyards. In a play of varying heights among courtyards and classrooms, the spaces leave the wooden beams visible. The prefabricated elements made it possible to reduce building time.
