On a busy road in Tokyo, High Land Design has created a little sanctuary. The House In Aoto, built on a  small plot of land, revolves around a stunning spiraled staircase. Each floor provides a distinct function, with the staircase allowing seamless movement throughout all the spaces and offering a tunnel of natural light. It is an inventive way to simplify vertical living. And, with the stunning geometries, a real jaw dropper as well. [Arch Daily]
