The design of Ukiya (浮家, meaning “floating house” in Japanese) embodies a unique philosophy of space as a foundation for dreams, self-discovery, and connection to nature. Inspired by the flow of Oku, this modern house features a single-plane layout that combines convenience with seamless spatial flow, offering a deep connection to its surroundings.
Nestled among rocks and trees, Ukiya boasts a linear, compact form designed to lightly integrate with its environment. Its point-supported structure allows it to adapt effortlessly to the site and diverse topographies, making it a versatile architectural solution.
Crafted with local materials such as Asama stone (浅間石) and natural wood, Ukiya blends harmoniously with the landscape. The design leverages the 6th facade: glass prisms at floor level establish an uninterrupted connection to the forest floor, creating framed views of the changing seasons and inviting nature into everyday life.
More than a house, Ukiya is a retreat—a place to disconnect, reflect, and experience a harmonious, balanced way of living in the heart of nature.
The house also features an exceptional spa zone, which includes a sauna, hot and cold baths, a shower, and a pool. A thin layer of river pebbles submerged in water enhances the sensory experience, while the gentle rise of steam creates an atmosphere of tranquility and rejuvenation. The entire spa area opens up to stunning views of the surrounding nature, blending soothing sounds, serene visuals, and a feeling of complete immersion in the natural environment.
