The site is located along a large boulevard defining one of the major urban axes of Nagano City. The building is designed with low eaves along the boulevard and a rhythmically divided facade, in order to establish a human-scale streetscape. Visual transparency creates an active interplay between interior and exterior. This “seeing / being seen” relationship is established via open views of building activity from the boulevard, and open views of the adjacent plaza greenery and the cityscape from the interior.

The building houses the new City Hall and an Art Wing, linked by a corridor around a shared courtyard that enhances the activities of the visitors. Located on the opposite ends of the courtyard, the two functions serve as one integrated facility, sharing similar roof forms, materials and color. At the same time, the interior spaces enclosed in the auditorium and the city hall offer different characteristics and functions, which are reflected in their distinct facades.
