Hephaestus' Cabin (#9) looks like a small factory, with brick walls and smokestacks like the forges and lots of gears around the entrance.
Inside: Leo describes the folded steel bunks against the walls to be like "high-tech Murphy beds". Each bed has a digital control panel, blinking LED lights, glowing gems, and interlocking gears. It has shiny metal walls and metal slated doors. It is noted for being unclean and messy, filled with junk most of the time. A fire pole comes down from the second floor. A circular staircase leads down into some kind of basement. The walls are lined with every kind of power tool imaginable, and a huge assortment of weaponry. A workbench overflows with scrap metal, screws, bolts, washers, nails, rivets, and a million other machine parts. There is also a tunnel underneath. It is associated with Bunker Nine. The most famous demigod son of Hephaestus was Archimedes
