Designed for a young couple living in the center of Tokyo, the T House does away with your usual walls and partitions, leaving every room open (except for the bathrooms, of course).

Gaping entrances help to connect different living spaces, while small rooms projected to the side are accessible via the main bookshelf-staircase and ladders. However, the thin ledges without railings or support structures will probably have to be modified if this couple intends to have kids in the near future.
