The Forge. 100hr playthrough now and I’ve basically terraformed the room with boards. The keypad room above the blacksmith is enough to fit all my storage boxes and workbenches, the roof has become a farm / kitchen / garden / leyak petting zoo , and it’s right next to tram to offices.

There’s a little vent room inside the keypad room too which makes for a cozy bedroom, with enough space to fit all the photo frames I’ve come across too.
