Edward Balcells, Ignasi Rius, and Daniel Tigges worked together on this new building housing the kindergarten and the communal spaces of El Til-ler, a Waldorf-Steiner school in Bellaterra, in the Catalonian municipality of Sardañola del Vallés. Arranged along a zigzagging high street, the timber-clad volume is the result of recycling five buildings belonging to the school. These were dismantled and transported to the spot for reconstruction, with a configuration adapted to the topography and other conditions of the new location. The open plan concentrates a number of thick pillars along the perimeter, forming buttresses. The spaces in between are designed differently, addressing pedagogical and programmatic needs (with benches, shelves, cupboards, tables…), and present themselves to the exterior as frames, giving the facade a dynamic appearance. On ground level, accessed directly from the avenue, are the school’s shared spaces, including the library, administration, and offices. The preschool classrooms are upstairs, reached by means of footbridges that solve the problem of grade differences.
