Y-BIO habitation is created for chill-out at hot and windy seaside of Crimea peninsula. It consists of tetrahedral demountable modules that are stable without any foundation footing. In addition, Y-BIO central house is hanged up with 3 chains to 3 vertex of 3 tetrahedron and doesn't touch the ground with its bottom. Morning airflows make a house swing, lulling a human sleeping inside. At night Y-BIO appears as aroma steam bar, where hot vapor goes through herbal mixture, entrains volatile essential oil, and turns into a fragrant warm steam for breathe and inhalation.
