AD joins architect Masato Igarashi of IGArchitects to see how he makes the most of his small Tokyo home. Tokyo has the highest population concentration in all of Japan, so large plots of land have been divided into two or three across the city, making tiny living the reality for many residents. While his home is technically only two floors, Igarashi fits an impressive seven staggered levels into the home with no walls, creating an open space where the seventh floor feels like the same room as the first.
