Extra-/ terrestrial Architecture is concerned with the development of design to construction approaches by transferring advanced technologies from terrestrial to extraterrestrial applications and vice versa. The focus is on the integration of advanced computational design with robotic techniques in order to produce highly performative architectural formations operating in a range of extreme to moderate environments. This requires that the design is directly linked to building production and operation relying on Design-to-Robotic-Production-Assembly & -Operation methods developed in collaboration with experts from computer, robotic, and material sciences in the Robotic Building lab.
