The layout illustrates the differences between a traditional two-storey Japanese house and its modern counterpart.
Overall, the traditional house has a more compartmentalised layout, with separate rooms featuring tatami flooring and sliding doors, whereas the modern house adopts a more open-plan design and includes additional facilities such as extra bedrooms and bathrooms.
On the ground floor, the traditional house contains a kitchen and a bathroom located near the entrance, as well as a tatami room with a cupboard for storing futons. In contrast, the modern version features a larger living and dining area alongside an open kitchen and tatami floors, which appear only in traditional rooms. While the traditional design relies on sliding doors and multipurpose rooms, the modern house includes clearly defined functional spaces.
Regarding the second floor, the traditional house comprises two tatami rooms with built-in cupboards, whereas the modern house has been reconfigured to include three bedrooms and two bathrooms. Notably, the staircase remains in the same position in both designs.
