Lighting Products and Fixtures Design Euphoria Retreat Spa Lighting Design by Anna Sbokou and Matina Magklara The Spa at the Euphoria Retreat, is located in Mystra. It is a four-story building, of 3.000 m2, that is carved into the base of a mountain. The lighting for each space was considered as a unique piece, contributing to the crescendo of the ultimate relaxation experience. As daylight would vary substantially from one space to another, custom luminaires were designed to imitate daylight conditions, thus harmonizing the transitions through spaces and enhancing the immersive architecture.
