The genkan is a Japanese-styled entry, which is lower than the main floor level where people leave their shoes on entering the house. The Japanese bathroom combines a sit-down shower and sunken baths for soaking. Tatami rooms or tearooms are found in every house in Japan, incorporating tatami floor covering and shoji screens to partition the room from the rest of the house. This room doubles as a guestroom where futons can be laid out on the floor. The shoji screen makes an easy divider between rooms and utilise the space effectively by sliding out of the way when not in use.
It can be cleverly used to divide a hall from a room and reversed to create a hall. When built into a wall and illuminated from behind, it not only warrants room but create a stunning visual feature.
