The demonstrator itself is doubly axis-symmetrical and has a square base area with an edge length of 5.10 m, measured on the outer side of the structural plane. The floor height is 3.0 m. The clear room height depends on the ceiling superstructures, some of which are also part of research projects. In the floors with conventional wooden ceilings, a clear room height of approx. 2.60 m is achieved.
In order to execute the demonstrator as puristically as possible, the vertical access as well as all cables are routed externally via a staircase tower. This is very similar in its dimensions to the demonstrator, but is built without a facade. Accordingly, all storeys are accessed via walkways. The distance between the two towers is 2.70 m.

Structure and Facade
The demonstrator is designed as an experimental building. Not only structural aspects are tested, but also innovative facade systems. The sizes of the facade modules are adapted to a typical skyscraper size. 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 the same, only the side facing the staircase tower requires an access door. For the floors that are not covered with test facades from the outset, it is planned to install a textile primary facade as weather protection until the facades to be tested are also installed here during the course of the research periods. In order to ensure that individual facades can be replaced at any time, a facade crane should allow permanent access to the facade.
The demonstrator enhances year by year and its appearance succumbs to continuous change. In order to make this possible, flexible fixing points are worked out during the working planning and forwarded to interested facade companies as a template. When completed, the demonstrator will be the world‘s largest adaptive structure and the first adaptive building in the world. The public interest will be very high from the outset, it will not only be introduced to the scientific community through numerous publications, but will also be presented to a wider public through regular guided tours. It is therefore the ideal advertising space for any company.
The future experimental platform is to be built to the west of the existing experimental platform of the ILEK. Together with the neighbouring ARENA 2036, the Sol Space Pavilion, the existing ILEK platform and the landmarked ILEK tent, it forms an „innovation mile“ that accommodates a large number of research projects on one axis and makes them accessible to visitors. As one of the tallest buildings on the Campus Vaihingen, the demonstrator together with the associated staircase tower will attract a lot of attention and will be visible from a distance (e. g. from highway A8).
The test platform will be 20 m x 27 m in size. In addition to the demonstrator and its staircase tower, containers for technology and monitoring will also be positioned, as well as storage space for functional samples on the platform. Access to the platform will be granted to visitors by appointment.
In contrast to all other buildings on the campus, which are oriented north-south, the demonstrator will be aligned in the main wind direction (west/south-west) in order to reinforce the existing wind influences on the building.
