A new building project for the Ministry of Finance of the State of North Rhine-Westphalia and other state users is to be built in the future on a site near the Rhine in the center of the government district and as part of the "Blue-Green Ring". Part of the project is the first wood-hybrid skyscraper in planning in Europe with a total height of over 100m (Status December 2022).
Our concept places a tower and an atrium building on a connecting base building at the opposite corners of the site. In the west, at the foot of the tower, a three-story glazed main entrance marks the address of the new Ministry of Finance. From this corner, one can see both the state parliament building and all the way to the Rhine promenade. At this point, the topography of the design also incorporates the library oriented towards the northern park. This rises in steps and thus connects with the levels of the catering and conference area. The entrance to the atrium building is located to the east. The staggering and greening of the so-called "Harold terraces" results in a great quality of stay. Here, for example, there is the possibility to hold open air events. Together with the adjacent open spaces of the "Harold Bay", a generous open space is created, which completes the "blue green ring" of on its south side.
The design proposes a homogeneous façade, whose idea horizontality reproduces the stratified levels and allows the views of the park and the city. The sustainable façade concept responds to the different uses and cardinal directions. Similar to a hat brim, the geometry of the horizontal façade elements works. On the one hand, they are inclined to generate the best orientation for the use of solar energy and at the same time provide protection from direct sunlight. On the other hand, to the north, the "brim" is reversed and opens to bring a lot of light into the building. Between the horizontals, a system of opaque wooden elements and metal lamellas envelops the building to protect it from eastern and western solar radiation and to give the structure a homogeneous and abstract appearance. The louvers are set back on the north and south facades to create space for vegetation in the north and to allow photovoltaic panels in the south. The flat roofs will be greened.
