Blau is a tensioned structure composed of a single membrane with three leaf-shaped openings. These openings provide unique lighting and spatial qualities that enhance comfort conditions in the courtyard. Due to its design, the structure maintains exceptional stability.

It is a tensile structure anchored along its entire perimeter to the concrete slabs of the main building, securing both the upper and lower cable systems.

The school has expressed the need for seasonal disassembly of Blau. The proposed solution consists of a single surface with three fusiform openings, preventing the accumulation of hot air pockets at the top of the courtyard while also allowing direct views of the sky. Blau is designed to accommodate the varying heights of the three adjacent buildings and the level differences between the two longitudinal sides of the courtyard.
