SIGN!, Office skyscraper in Düsseldorf Hafen, Germany.
SIGN! is a modern office building in Düsseldorf's port district, rising 19 floors with a height of 76 meters. Its glass and steel facade defines the look of the harbor area.
The building was completed in 2011 as part of the modern transformation of Düsseldorf's harbor that started in the early 2000s. Its completion marked an important shift in the area's development as a business center.
The building design by Helmut Jahn incorporates elements of German precision engineering while maintaining a strong connection to its waterfront location.
The building sits in the port's business district and is easily reached by public transportation. Its close proximity to harbor facilities and the waterfront makes it easy to explore the area.
The vertical lines of the facade create changing light patterns on the glass surfaces throughout the day. These effects emerge from shifting sunlight, which emphasizes the building's geometric form.
