The two architects Mauricio Pezo and Sofia von Ellrichshausen created a new innovation centre on the Collao Campus of the University of Bío-Bío in Concepción (Chile). With the design, they wanted to show how a simple multi-storey building can become spatially complex. All six floors are slightly different as the proportions of the circles gradually change from floor to floor. “This is an apparently simple, stable and regular building that contains an unexpected and exaggerated interior,” said Pezo and Von Ellrichshausen.
