In the wake of the pandemic, more and more people were forced to work from home or elsewhere. Without the commute, the boundary between office, home, and even school becomes blurred and gradually merges together with the help of technology. To adapt to constantly changing needs and maintain the dynamics of our working and living space, a track system is introduced that provides ease of operation and directional flexibility, enhancing the versatility of interior space. This architecture is intentionally designed to be “roomless.” Inside there is no static accumulation of rooms, but merely a dynamic and changeable open zone full of “domestic units and events.” In a “roomless” space, the definition of space is dissolved and re-merged into modularized furniture components, movable partitions, and objects. Based on the user’s preference, the overall interior configuration can be personalized. A wide variety of possible permutations of furniture, objects, and partitions moving along the track system provide various spatial experiences and living qualities.
