This villa is located at the innermost edge of Lake Biwa, Japan’s largest lake. By introducing small paths that cross the site and distributing functions across four buildings, the entire site is designed as a single, immersive environment. The property includes four areas: the main house (living, dining, tatami room), an annex (main bedroom), a spa wing (sauna, lounge, bedroom), and a Zen wing (meditation room, outdoor living space). Together, these spaces create a villa that allows residents to move freely according to time and mood.
