The main structure of the hotel is a combination of in-situ concrete and a steel construction. The concrete core provides the stability. To this, the steel construction is hung, at the location of the partition walls of the hotel rooms and on all floor levels linked with the intermediate precast concrete floors. The roof of the top floor, a technical room, is made out of steel. The supporting structure of the car park consists of concrete retaining walls and steel columns; the roof of hollow core floor slabs.
