UPPER WEST, Berlin
How to ensure 24/7 usage of a high-rise?
Flexible living and working are becoming ever more important and popular in our cities. However, desirable urban centers afford little space for new buildings. It would therefore seem obvious to stack the city upwards, would it not? In Berlin’s vibrant City West retail, a hotel and offices are stacked on top of each other up to a height of 118 meters in one of Germany’s first hybrid high-rises. It is highly efficient to integrate different usages into a tower, and ensures urban space is filled with life. In urban planning terms, the Upper-West-Tower is divided into two sections, an eight-story office and commercial building facing Breitscheidplatz and a 35-story high-rise with a hotel and offices.
The greatest challenge when stacking different usages in a high-rise is access to them – as each section needs to be accessible from the street through its own separate foyer. For this reason, we focused specifically on coordination and planning of the access shafts. This is what decides whether a high-rise is efficiently planned and can be used well. Moreover, we devised a uniform axial grid for all areas – it functions optimally for office, hotel, and retail usages as well as for the underground carpark. The result is a flexible building that will have a long service life and is therefore sustainable.
