A three-story tubular house with three propeller-shaped planes. In order to construct the curved walls of the walled reinforced concrete structure, a chimney construction method called metal form was adopted. In order to create a cylindrical frame composed of different curvatures, the arc was divided into straight lines at the points where it changes, and the steel formwork was used to approximate the polygons. Inside the building, three rooms with arched shapes and openings connecting them are connected to create a single space.
