Actually, the building was not the machine. The building was there for isolating the machine from vibration and from changes in temperature and humidity. The building was an anchor.
Long dimly lit corridors nearly a mile long with 3 stories of machine next to you. Air rushing through vents making a constant soft hiss of air. Outside that room, rows of tanks with jackets, and lots of pipers and pumps running to the coating machine in the next room.
Guys in white suits and special shoes stalking up and down these corridors. Ladders to the tops of the tanks, with metal platforms around them.
Lots of fun doing these things, knowing that we were making something that was liked by you guys.
