This simple looking small house can be found in one of Tokyo’s high-density residential areas. The house was built on a small plot of land and has a total useable floor space of just 670 square feet (that includes the ground and first floor). The house was designed by Japanese architecture firm, Case-Real, who were asked by the client for the southern end of the home to be filled with light. To address this requirement the architects introduced a hexagonal floor plan that allowed the sunlight to shine continuously into the living area from dawn to dusk.” – Niall
