When the trailer is unfolded, it can be connected to other trailers of the same type, which makes it possible to create a modular system for different needs. By connecting several trailers, we can create flexible living units, where each trailer has its own specific function Living one can serve as a bedroom, another as a kitchen or living room - Medical: one serves as an operating room, another as a surgical room, the third as an intensive care room and alike. Army: one serves as a control center, the other as a strategic center or all can function as a full part. This modular approach allows flexibility according to the needs of the users, as the system can be expanded or reduced according to the number of people or activities. In this way, it is possible to create a flexible mobile settlement that offers multi-purpose use in one compactly designed space.
