We attempt to make the living return to the most primitive state. We can imagine that ancient people lived in cave dwellings, and the same materials are used in all spaces and the life of appliances. There are no straight lines or right angles in the space. Stretching of the visible space is created due to the changes of time. Through the digital operation, the plywood is wholly designed in the sales office and the sales tools, which creates the theme and uniqueness for the visual experience. The same materials and techniques are applied in walls, tables, as well as bars.
