Japaneseword “shinkan” means “deep stillness” . It expresses a way of falling completely silent without making a single sound.Therefore, we focused on sounds. By eliminating all the noise we tried to create a sauna space where one person can relax.The partition walls extend to the attic, all finishing are uneven, and sound proofing material is used inside the walls to minimize noise.Furthermore, by applying lighting that corresponds with a direction, intensity, color temperature of the natural sunlight, the space was designed to express the silence of a naturally born and growing forest.
