The Dutch hotel chain “Sir Hotels” had an eleven-storey office building at Katharinenstrasse 29 (Nikolaifleet) in Hamburg converted into a 5-star hotel. The name of the new luxury hotel is “Sir Nikolai”.
As a special highlight, the atrium was fitted with an opening Cabrio sliding roof, in which the two middle sections can be moved over the fixed sections in an extended rail system. This means that the opening is larger than the fixed glazing.
The opening is planned for winter 2016 / 2017.
