Density by Jun Igarashi
Density is a minimalist house located in Hokkaido, Japan, designed by Jun Igarashi. The narrow home is centered around a spiral staircase, and features small nooks and lofts totaling 32 rooms. Despite the size restrictions of the lot, the architects did not want the home to be completed without some interaction between interior and outdoor space. As a result, a small courtyard is carved out in the middle allowing the residents to go outside for relaxation or reading.
