## Abstract

An expandable structure includes an expansion section having walls that can stack into and be deployed from a wall enclosure central housing. Linear actuators can be deployed on the wall enclosure for facilitating the movement of wall panels into and out of the central housing. Each linear actuators can be easily dissembled out of the structure for maintenance or future upgrade. Concurrently, the linear actuators can work in synergy with a precision track system, ensuring the precise displacement of each individual wall panel. This innovative configuration not only enables efficient and accurate storage of each wall panel within the central enclosure but also concurrently serves as the foundational support structure for the cabin.
