Since the call for tenders in 2012, it was clear that the Secondary School Sandgruben would be no ordinary school. The initiative seemed to be steered by a team of idealists. In the preface to the call for tenders, classroom planner Stephan Hug called for an ‘intensive dialogue between the partners involved in the project’. To support this, he quoted architect Alfred Roth, who traced the ‘poor development of the school construction question’ back to ‘the lack of cooperation between education professionals, architects and public authorities’. This quote from Roth is now nearly 60 years old, and the team of idealists, who can better be described as visionaries, actually succeeded in using this ‘intensive dialogue’ to create new pedagogical approaches.
