Abstract
This paper describes the architectural design of the ventilation buildings of the immersed tunnel at Niigata Port, which is under construction to solve the absence of a road connecting the right and the left banks at the estuary of the Sinano River. The ventilation buildings will be new landmarks at Niigata Port with 40 meters high and play a leading role ih the composition of the landscape. These are composed of four towers to reduce the impression of a large, overpowering structure and maintain a feeling of familiarity. Also, these shapes are designed to vary towards various view points.
