Abstract: Modular building structures and methods of forming such structures are disclosed. A modular building structure may include a plurality of walls, a ceiling and a landing. The plurality of walls may include a front wall. The ceiling may be positioned at a top portion of each of the plurality of walls and may have a top surface. The landing may be connected to the ceiling by one or more pin assemblies. The one or more pin assemblies are configured to enable the landing to be moved between a retracted position and an extended position. An upper surface of the landing may be adjacent to a top surface of the ceiling when the landing is in the retracted position. The landing may extend from the front wall when the landing is in the extended position.
