The idea is to re-design two classrooms of the ISAD (Instituto Superior de Arquitectura y Diseño). First the activities that occur in the classroom were studied, the result was that there are two main groups of activities 1st audio/visual learning (passive) and 2nd didactic learning (active), for the adequate conditions of each activity is almost impossible to have a single space for bout so a third space is proposed besides the classrooms, a expositions and presentation space which can be opened for expositions and it can be closed for presentations or projections and the two classrooms are transformed into co-mutual workshops.
