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 equipped with a Cabrio glass sliding roof that can be opened, in which the two middle parts can be driven in an extended rail system over the fixed separators. Thus the opening is larger than the fixed glazing.
The opening is planned for winter 2016 / 2017.
