The Göttingen Experimental Laboratory for Young People - XLAB - was given a building suitable for it, that means an experimental building. Almost cube-shaped, it dominates the new center of the northern university area and with its strong colors breathes a bit of colorful life into the gray campus. Supported by four "elephant feet", a prestressed concrete grid floats above the roof, from which the edges of the ceiling are suspended on thin steel cables. The suspended house enables a formally completely independent ground floor and the point-symmetrical rotation of the upper floors around the central atrium. The sky can be seen through the highly transparent foil cushion roof.
