A building's exterior wall is composed of vertically ridged gray panels with a large, rectangular opening. Inside the opening, there's a gray ceiling with various pipes and a small ladder. The opening is framed by the same vertically ridged panels, creating a balcony-like appearance. At the bottom, a row of yellow and black blocks provides a safety barrier. Overhead, air ducts extend above the building's edge.
