The Open Architecture Challenge is an open, international design competition and is hosted every two years on the Open Architecture Network. This year, the challenge invites architects, designers, students, teachers and parents to propose the classroom of the future. Anyone can participate and the winner will receive $50,000 for their school.

Juan Herreros (from former Abalos & Herreros) won the 2nd place on the international competition for the new builings of the CEA Cadarache Research Center. Long buildings reduce the impact of the construction in order to keep the forest density.
