The school, which was built in the 1960s, is situated in a heterogenic urban environment with extremely varied development structures and several green areas. In order to reinforce and further define the site, the design for the expansion foresees a second building, which is parallel to the existing structure and nearly corresponds with it in length, breadth, and height. Together they form a unit that utilizes the entire land area. In this way, on the one hand, a highly concentrated urban space emerges, and on the other hand, between the two school wings, a protected sports and break area which is lowered one story, and thus perceived as a comparable volume. The main entrance is on the front side of the new building and flows into a two-story hall from which all areas of the school can be accessed. Through the specific arrangement of the various areas, such as library, cafeteria, educational center, gymnasium, etc., different uses are possible, and spaces with a high communicative potential emerge. In terms of construction, the new building contains six load-bearing cores, four longitudinally stressed, twostory steel lattice girders, and in the area of the outer walls, reinforced steel supports, which span the ground level and basement with sports grounds, thereby enabling their column-free, largely transparent formation.
