The change in the science of education and the reinterpretation of teaching methods prompted the City of Dortmund to examine the future viability of the Reinoldi Secondary School's location and the main building, which has been extended in several stages but has become outdated. The analysis recommended a new building. The U-shaped building is invitingly positioned towards the schoolyard, but was moved away from the street and positioned towards the rear of the school campus. Together with the gyms and the natural sciences extension, the main building forms an urban unity.
