FOLDABLE SUNKEN HOUSE STRUCTURE

An expandable home structure includes a main structure and a first expansion section that is expandable outward in a first direction from a first side of the main structure. Once the expansion section is expanded, coverage members can unfold from a bottom of the floor member and the floor member can be lowered within the unfolded coverage members, thus providing a sunken floor for the expanded section. The floor member may fold vertically against the main section in the folded configuration. After the front and rear walls are unfolded from the main section, the outer wall of the expansion section can be moved outward from the main section to cause the floor member to lower into its horizontal, expanded, and raised position. The coverage members can be unfolded from the bottom of the floor member and the floor member can be lowered.
