A complex, intricate brutalist building divided in smaller part, like multiple buildings at once, with one linked entrance and inner-court with multiple heights, it needs to have acceses from the inner court and from around the building, you need to be able to visit this by doing a walk that goes at least in the inner court, in the buildings and somehow on a balcony or cage around the building itself to reach the rooftop.
