This paper model is a Moon Base, created by armadamodels. The scale of the paper craft is in 1:250. It includes modular accommodation / technical areas with access corridors, chemical storage tanks, and a control tower.
Although advanced sensing and monitoring equipment makes the requirement for an expensive control tower highly debatable, it nevertheless looks aesthetically pleasing! Also included is a shuttle-craft for ferrying equipment and personnel between lunar-surface and Earth-orbit.
