The $218 million project involved constructing a 51,000 sqm 5-star hotel tower in central Berlin consisting of a 32-floor tower with 250 hotel rooms, 10 floors of apartments, and lower level commercial space. Logistics were challenging as all materials and waste had to be moved at night due to the site's location. Design coordination was also difficult because interior design firms from Germany, France, and England were used. The project was completed in 2012.
