Atelier-OPA has created a series of rooms on wheels that makes living in small spaces easy. Each small cabinet expands into a full room of usefulness. One unit expands into a complete office workstation area, complete with filing cabinets, lamp, desk area, computer table, and more. The next cabinet transforms the same space into a kitchen, complete with sink, cutting board, and storage. The final cabinet may be the most incredible. This cabinet takes the same small space and turns it into a bedroom, complete with bed, cabinets, and a bedside table.
When not in use, each room collapses back into the cabinet to be set at the edge of the room. Rooms on Wheels are an important concept for areas of the world, like Japan, where living space is tight.
