The residential and commercial building in Hamburg´s Hafencity was built as a reinforced concrete structure with two lower floors and eight upper floors on a bored piled foundation. Under the construction site there is a subway tunnel (Line U4). The high demands on living comfort permitted only low vibration and secondary airborne noise immissions.
