The new city hall project of Shibata-shi, Niigata which has 400 years of history as a castle town. This project is expected to become activation of a central city area, and a starting point on which a tourist takes a walk. The building consists of three layers. The high part is a work room which appears like white clouds. The medium-rise part is a parliamentary function. The low layer part has a citizen service function. There is a half-outdoor open space called “FUDANOTSUJI” in the first floor.
