The Double Helix House is the perfect name to describe this spiral-designed home. It's located in the Yanaka area in Tokyo and it's not easy to find; it's accessible only from a small alley off a main road with twists and turns along the way.
Designed by Onishimaki and Hyakudayuki Architects, this house stands out amongst the others as its modern wood exterior jazzes up the facade that strongly contrasts the dull color in the area. The alley that leads to the house eventually turns into a passageway that winds up and around the home. This stair-wrapped house comes with no fitness room but it does have a lot of steps that'll provide endless exercise. The core of the home is a white cube structure where all the rooms reside and the end of the path is the roof top terrace with immaculate views.
