Earlier in 1960, GK had proposed Dwelling City, which was an embodiment of a space created by dougu according to
“Study of Dougu” that was the origin of GK Architect. The city is a plan having dougu for creating space that bears a human centered city surrounding an axis composed by housing named Dwelling City. In the idea, many housing units are composed like a huge shell as a whole to create the public space in its center. The networked dougu is assumed to make an infrastructure for utility supply and drainage freed from gravity, and makes the city possible to have a living environment with flexible net work. By restructuring Dwelling City through self-sustaining contemporary technologies, we would like to ask ourselves what fulfilled the living for Japanese as well as contemplating “should be” housing capable to flexibly respond to a paradoxical part of society such as overwhelming speed of aging, a natural disaster and energy.
