The main building ("corps de logis") is flanked by two wings that open towards the inner courtyard by way of arcades. In the direction of this "cour d'honneur" the central part of the main building extends quite noticeably, to accommodate the large central staircase. The middle pavilion of the main wing sits on a pedestal-like ground floor and features two full upper floors with high windows. The other parts of the building have only one main floor and one mezzanine floor, with the exception of the pavilions sitting at the end of the two wings, which have two main floors and one mezzanine floor (the latter housing the guest rooms). All the facades are covered by light gray sandstone, sculptures and window frames are made from yellow-greenish sandstone.
