Being a highly exclusive, design-oriented project, especially in the privately owned top-storey flats the wishes of the owners were of highest importance – also when it came to the façade design. Demands for individual window sizes or positions were to be regarded and respected, even on short notice during the running construction process. The Knauf Exterior Wall with AQUAPANEL® Technology was a highly useful solution to cover these demands. One of the system’s main components is the drywall construction board AQUAPANEL® Cement Board Outdoor. These cement boards are highly flexible, which starts with their handling, allowing easy cutting and snapping and also the construction of individual shapes like rounded windows. Thanks to this state-of-the-art drylining technology, the owners now can enjoy new perspectives of Stuttgart, from their exclusive Cloud N° 7.
