ANNA is modularly developed, which results into short construction time on site and therefor a minimal ecological disruption. Besides, ANNA is designed in such a way that 80% of her unique parts can in the future, via a digital file, be produced locally all over the world on CNC machines and 3D printers (mounting material). Furthermore, rubber and aluminium extrusion techniques were used, resulting into 26 for ANNA uniquely designed extrusion profiles to ensure that ANNA always slides perfectly and is water- and windtight. The most innovative part being the patented aluminium rails. Finally, following the principle of Thomas Rau's materials passport, all materials of ANNA can be completely separated and reused.
