Kaisanji, the temple (ji) of the mountain (san) and the sea (kai), will be located on Serifos Island, near the beach of Kalo Ampeli. The unique beauty of the natural landscape, the moderate and sparse construction, and the unobstructed sea view make this location ideal for establishing a center for meditation and spiritual upliftment.

Kaisanji will feature spaces for meditation, the initiation of visitors into the Zen tradition, and ceremonies such as the Zendo, the Hato, and the outdoor bell area. It will also include accommodation rooms for monks (cells), guest rooms, and a dining area. The primary goal is for it to be an autonomous and self-sufficient center, functioning as a summer accommodation to cover its operational costs. The dual function of the space presented the biggest design challenge, combining the austerity of Zen philosophy with the requirements of a modern facility.

The architectural design is inspired by both Japanese culture and tradition, as well as the unique architecture of the island. It emphasizes serenity, simplicity, and balance with nature. The intervention was kept to a minimum, with utmost respect for the natural landscape. In an effort to redefine the relationship between humans and nature, the concept uses natural elements as design tools. Planted roofs allow the vegetation to become an integral part of the building and blend seamlessly with the stone walls.

Water is a key design element, featured in forms such as the lake beside the Hato building and the flowing ‘stream’ that follows the natural slope of the land, culminating in a waterfall. The journey begins in the zen garden, where water, rocks, and pebbles are arranged in circular patterns, reflecting the principles of Japanese gardens. This liquid element enhances the sense of calm, while the gentle sound of the stream naturally guides visitors from the entrance and the Hato to the bell and, finally, the monastery’s core—the Zendo. Embracing the principle of endless motion, the energy generated by the running water, supplemented by an external source, is reused to return the flow to its origin.
