After intensive planning and research work from the end of 2021, the world's first adaptable skyscraper was opened. It is located on the Vaihingen campus of the University of Stuttgart. The demonstration skyscraper is 12 stories high and will also be part of the international building exhibition IBA'27. It was created as part of the SFB 2144 Collaborative Research Center "Adaptive Shells and Structures for Tomorrow's World" at the University of Stuttgart.
The building is about 37 meters high and consists of sensors and actuators that make it possible, for example, to use an intelligent control concept to compensate for vibrations in the tower caused by wind forces. This makes it possible to build much lighter than would be possible without the adaptability. The twelve levels are independent of each other. Furthermore, not only structural aspects are tested, but also innovative facade systems. The dimensions of the facade modules are adapted to the typical dimensions of a skyscraper. The floor height of 3.0 m also corresponds to the height of the individual facade elements.
Due to the double-axis symmetry, all four sides of the facade are equal, only the side facing the stair tower requires an access door. For floors that are not covered with test facades from the start, a textile primary facade is installed as protection from the weather. The building continuously changes due to flexible fastening points and is the largest in the world as adaptive and changing.  

"Due to the growth of the world's population and the associated increase in resource consumption," reads the University of Stuttgart website, "the construction industry, which is a major consumer of resources, can no longer shirk its social responsibility. Adaptability can play a key role in the construction industry in meeting this challenge. With this technology, the limits of lightweight construction are clearly overcome, because the use of adaptive elements makes it possible to build components with up to 70 percent less material than a passive component."
