A design floor consisting of three types of design, such as stream, amida and grid, is produced as a result of collaboration with the most attractive design office “Nendo,” an office of which has been received numerous worldwide design awards including ELLE and DECOR magazines. While taking advantage of the rich wood taste unique to Premium precious wood, a mood in the space with a unique individuality is created by the combination of vertical joints with horizontal joints and a wooden framework by mixing woods with different width.
