We covered a rectangular site in a residential area oriented at a 45° angle to the north and rotated the roof of the second floor on top of the rectangular first floor; then, we created a large window on the side at the south corner. To achieve an open interior with a limited footprint, we created a single‐volume space connecting the first floor to the second floor with stairs. The timber frame of the second floor sits on the concrete box of the first floor. The stiff timber box consists of a folded roof and exterior walls to achieve a large pillar‐free space. We set the main windows higher to maximize the effect of natural light, placed eaves in front of the large window to block direct sunlight, and used slit windows between the first and second floors to promote natural lighting and ventilation.
