Can you imagine if every room in your house had its own garden? If you lived in a palace, mansion, or manor house, perhaps. But what if you lived in a 13-foot-wide, five-story house in a commercially dense section of Tokyo?

Composed of a series of structural slabs and glass walls, this house and workplace designed by Japanese architect Ryue Nishizawa appears wall-less and light-filled; perfect conditions for the plants in all those gardens.
