Helix city plan was designed by Kisho Kurokawa in 1961 during the early years of the metabolism movement. The city is more commonly known as the floating city because it is placed on the ocean. Kurokawa’s vision for the city was to have an organic city plan, having the land and water building structures to be connected only by bridges. The form of the spiral structures resembles DNA. The apartments in the structure are hung within the spiral to fill the spaces.
