Our second space architecture project ; Lunar communal housing project has done. It has done for Kim Kyunghwan’s master’s degree project. At the very beginning, Bernard Foing from ESA gave us an idea about ice shell housing. Then we mixed the idea of water membrane system and regolith structure to making a “hybrid facade.” A space architect, Brent Sherwood from JPL of NASA helped us for the scientific and technical advice. And for the long temp development, we proposed infrastructure tunnel which has “Hyperloop” (transport capsule) and public space for the respirable exterior without a spacesuit. We will present at the #IAC2018 in Bremen, Germany. The English version and more photos of models will be updated.
