The four free-form roof shapes of the Hungerburgbahn resemble the snow-covered landscape surrounding the city of Innsbruck. Each roof comprises a steel structure and a glass-panelled shell floating on concrete plinths.

The load-bearing steel structure comprises precision-cut steel sheets. The double-curved shell is clad with opaque glass panels mounted to the structure’s joints. Smoothly shaped volumes without visible glass fixings emerge, bearing on only a few points on the concrete structure beneath. To a great extent, the planning process is digital based on an integrated three-dimensional computer model directly connected to predominantly automated manufacturing.
