In contrast, the tatami flooring, sliding doors, night time, cupboard room with futon and door continue to be used to ensure functional continuity, whereas unfolded futon and are added.
In the upstairs, there are significant changes in these areas, with the destruction of almost all rooms for cutting-edge areas. In terms of room designs, the previous rooms have been established to match their sizes and expanded from 2 to 3 bedrooms, including the addition of 2 bathrooms.
