Built in the 1970s, the existing school campus and its generous outdoor facilities are highly prised by students and teachers alike. Accordingly, the choice for the winner of a competition to expand the school was based on a solution that protected the grounds. The solution lies in vertically extending the existing buildings, creating an integrated mix of new and old.
The generous exterior space, well embedded in the landscape, is preserved in its entirety. The financial budget for the exterior spaces is to be fully used for their improvement. The prudent use of land resources, minimal use of grey energy in construction, and centralisation of the school complex make the concept of vertical densification a multifaceted sustainable strategy.
The design of the existing access road is a remnant of traffic-oriented urban development ideologies of the 1970s. With the relocation of the parking areas on Riedstrasse, traffic is removed from Hellwiesstrasse, which is transformed into a pedestrian zone, a “Learning Boulevard” that extends across the school grounds and on towards the adjoining Chimlibach neighbourhood.
With the introduction of the new “learning landscape” and shared-use classrooms, more students can be taught. The free plan of the learning landscape enables different forms of use and learning concepts. It offers space for informal learning, learning aids, and group work as well as extracurricular uses or events. A new gymnasium is also being built.
The new extensions are constructed in wood. This ensures low weight loads, high prefabrication percentages and short construction times that minimise disruption of the ongoing school operations. The extensions give the existing school a stronger urban presence and create a spatially defined centre.
