The building comprises three asymmetrical trapezoidal shapes – two stone elements and a glass body between the two for the pool hall and the entrance foyer. The focus of the pool hall is a 225 square metre indoor and outdoor pool in one with a heated water pool, bubble beds, massage jets and adjacent areas for relaxation. The glass façade, oriented to the south, opens up the view into the Menzenschwand Valley and enables passive use of solar energy.
