Two-direction expandable mobile house

An expandable structure transformable between a stowed state and an expanded state, the expandable structure comprising:

• a main structure;
• a first expanded section, the first expansion section expandable outward in a first direction from the main structure;
• a second expanded section, the second expansion section expandable outward, in a second direction orthogonal to the first direction, from the main structure;
• a third expanded section created at a corner intersection of the first expanded section and the second expanded section, the third expanded section formed when the expanded structure is in an expanded state;
• a first roof member covering a main structure in the expanded state;
• a second roof member covering the first expanded section in the expanded state;
• a third roof member covering the second expanded section in the expanded state;
• and
• a fourth roof member covering the third expanded section in the expanded state, wherein:
• the second roof member at least partially nests with the first roof member in the stowed state;
• the third roof member at least partially nests within a slot in the first roof member in the stowed state;
• and
• the fourth roof member at least partially nests within a slot the second roof member in the stowed state.

• a first floor member forming a first expanded floor surface in the first expanded section when the expandable structure is in the expanded state;
• a second floor member forming a second expanded floor surface in the second expanded section when the expandable structure is in the expanded state;
• and
• a compact floor portion stored within the first floor member of the first expanded section, wherein
• the first floor portion is pivotably attached to the main structure on an interior end thereof and is pivotably attached to an outer wall of the first expanded sections;
• the second floor portion is pivotably attached to the main structure on an interior end thereof and is pivotably attached to an outer wall of the second expanded sections;
• each of the first and second floor portions slidingly engages respective outer walls of respective first and second expanded sections;
• and
• the compact floor is expandable to form a third floor surface of the third expanded section.
