The design of the Harbor gate Münster deals with the last vacant lot on the south side of Münster's city harbor, the area where the Dortmund-Ems Canal enters the harbor. In accordance with this exposed location, the planned development takes up existing references of the adjacent northern and opposite building edges. With its staggered heights, it creates an accentuated end point of the south bank. Together with the high-rise building planned on the northern bank, it creates an inviting gateway situation to the city harbor. The building complex is accentuated by two high points, which are designed as towers. The volume connecting the two towers begins at the height of the lower development on the south shore and then rises to the northeastern high point. The building volume is differentiated and structured by incisions. Light enters the building through the incised courtyard and the atrium. At the same time, these two areas in their interplay form the center of the building.The utilization structure of the building is designed for a multi-layered and sustainable use. In doing so, utilization units of different characteristics and sizes are created. Due to the even distribution of the escape staircases, the utilization units can be designed variably to the greatest possible extent. The variability is supported by the regular load-bearing structure and the open floor plan design. In addition to a gastronomic use on the ground floor and 1st floor, there are flexibly designed office spaces, studios and workshops as well as central uses consisting of seminar rooms, event rooms and presentation areas on the floors. The facade design of the building is characterized by a massive base as well as an alternation of transparent and translucent facades. Material references of the existing and historical buildings are taken up. The material concept is based on the fundamental idea of sustainable and recyclable construction. Recycled materials were therefore deliberately selected for the facade materials. For example, the facing brickwork is made of recycled clinker. The translucent facade is defined by glass ceramic panels, which are also made of fully recycled glass.
