A strong plasticity with high-quality, sustainable materials and repetitive elements give the mixed-use building at its exposed spot on the Rhine river bank a homogeneous, unique and powerful appearance. The design moves between the two poles of the individual characteristics of living and office spaces and a symbolic unity: Both aspects of usage have their unique expression yet unite to an overall design, confidently claiming its space within the architectural surroundings. Materiality and coloring aim at a robust atmosphere matching the rough character of the immediate environment. The strict separation of the gardens is designed to blur over time.
