Transustainable House is a minimalist home located in Tokyo, Japan, designed by SUGAWARADAISUKE. This project shows a new solution for sustainable architecture that metamorphoses its existence over the time. In Tokyo, it is quite typical for a house to be built on a very small site. Therefore, in order to maximize the limited dwelling space, this house expands the dwelling space both inside and outside, and converts the entire site into a group of spaces with different qualities.
 Private rooms are placed diagonally in the site, while common areas are created between them, transforming the rest of the site into ‘semi-indoor’ residential area.
