This proposal focuses on the large number of vacant and underused houses in rural Japan.
The assumed condition is an empty house without active utilities, where reconnecting water and electricity would be costly and impractical. Instead, the project introduces a self-sufficient trailer-based system as an external intervention.

The trailer contains three independent units—a bedroom, an entrance, and a bathroom—which can be physically plugged into the existing house.
These units can be inserted individually or in combination, allowing different spatial configurations to emerge over time and enabling the vacant house to function as a weekend home or holiday retreat.

Living is no longer understood as a fixed condition, but as an adaptable process—spaces can detach, reconnect, and evolve.
By bridging real estate and mobility, the project reactivates vacant houses through minimal intervention, proposing a new mode of inhabitation that balances independence and continuity, permanence and change.
