The architectural firm Stephen Williams Associates has just completed the interior designing of 25Hours HafenCity in Hamburg, Germany. It's part of the HafenCity project, the largest development building project in Europe in the 21st century, aiming the creation of a new urban environment in Hamburg's old harbour. The decoration is inspired by the rich maritime history in the area. It features 170 suites, rooftop gym/sauna, restaurant, bar, art gallery, private wharf and a conference room.
