This project is a reproductive medical center in Nagano, Japan. Adopting the medical philosophy of adjusting the body cycle naturally, the clinic is layered with a light ceiling that is made of wooden trusses and translucent ceiling layer that change its appearance in every moment according to the provision of natural sunlight. Almost no column is plotted in the internal space, the wooden trusses that span across the building allow free planning. The longest span truss in the center is at maximum height of 1.7m and gradually decreases according to length of each span. The plenum space which carries various air volumes becomes a light pool that changes depending on time of day, weather, and season of the year. The translucent ceiling layer promotes diffusion and reflection of light.

The Mibu River flows to the south of the site, and the Southern Alps mountain range is far to the southeast. The shape of the site is similar to a parallelogram, and the building is laid along to it. Structurally, it is more efficient to set the axis of the gantry trusses to the short side of the diagonal shape and direct the view of the spaces to southeast. The elongated shape wall changes its visible area depending on the line of sight, creating both openness and closure at the same time.
