It is a house for a young couple who is raising a child, built in a place where agriculture and housing are mixed, just over an hour by train from Tokyo. Since the vineyards that extend in two directions on the site are designated as production green areas, it has been promised that a stable environment will be maintained for a long time. Here, we planned a house as a place where indoors can develop a life that slides below the vineyard. Rather than living in a house, it is an image of living in an environment including the surroundings.

As a result of securing the ceiling in a form that is continuous with the trees in the vineyard, the floor level on the first floor is 70 cm lower than the surrounding ground. All four floors on the first floor are glass-laden and look at the sky through the branches. In the distant view, only the second floor part comes out of the vineyard.
The room was finished mostly with a paint close to black so that the outside could be felt approaching. The structure is established by the calculation of the wall volume of the conventional wooden structure, and the outer peripheral part is only subjected to the weight by the steel pipe of φ = 42.7 mm. By using the foundation in the reverse direction, it is used as the waist wall of the sunken part.
The plane is a studio that surrounds the core at noon. At night, you can divide the place to sleep, the bathroom, etc. according to the activity and divide it into nine. When you go to the roof, you will see a completely different view from the ground over the vineyard.
