Building B was one of two warehouses owned by Rampone Dockside Shipping in the Wayside Docks. The ground floor consisted primarily of a large storage room, with two large workshops in the northern end of the building. The second floor contained two more workshops in the north, with administrative offices in the south end. The third floor consisted only of president N. Rampone's office and a conference room.
The Mechanists had rented out all four workshops in Building B, and even used some of the storage space on the first floor. Rampone supervisor J. Osterlind and Captain Davidson used the storage room to covertly smuggle spice.
Building B was connected to Building A on the second floor via a covered walkway and an outside catwalk.
