The elliptical administration building is in direct proximity of the lock Bellevue: two Solitaere, which face each other independently. The circle and the material of the outer skin, dark, polished natural stone, contribute to the fact that the building becomes part of the park landscape. The outside wings of the wood box windows, which sit concisely in the front, can be opened outward. The bright interior is divided into four lying on top of each other office rings, which itself around a glaesern considered, huge resounds with development core puts.
