Concordia's engineers meet here to work and discuss future ideas for the island. Their research ranges from buildings to weapons. You'll find quite a few of the Hephaestus and Vulcan kids here, even if they aren't formally working as engineers. The basement is set up as a forge and testing area for smaller projects while the top two floors house the individual offices and work spaces. There is also a relatively large lot fenced off in the back for anything that isn't safe to set off in doors.
