Back to One's True Nature, a duplex residence a couple shares with their mother, features a design that maximizes the layout's openness and brightness. Hallways dividing the space are reduced, and the main and secondary flows are configured based on functional needs. Thus the space becomes a container of life centering on its dwellers' daily habits and needs and is divided into the main and secondary domains that encompass both a private area for personal use and a shared section for the family to interact.
