On behalf of the project developer Hines, 206 rooms, a foyer and bar area on the ground floor and a spacious roof terrace were realised on the 13 floors for the Ruby hotel group. Built at the beginning of the 1960s by the Düsseldorf architect Paul Schneider-Esleben, the high-rise was listed in 1998 especially because of its innovative curtain wall facade. It is considered the first elemental high-rise facade in Germany. As part of the conversion, the facade was renovated in close consultation with the listed building authorities and was able to retain its historic appearance while meeting the latest standards of energy efficiency and user comfort.
In addition to the delicate facade, the monumental exposed concrete structure, which is also visible from the outside through the fully glazed ground floor, is essential for the appearance of the building. "The light glass facade also enabled the traffic zone below the tower to be integrated inside the hotel. Therefore, the forecourt visually continues into the hotel lobby," explains the responsible HPP Senior Partner Volker Weuthen.
