Lighting Products and Fixtures Design Euphoria Retreat Spa Lighting Design by Anna Sbokou and Matina Magklara Euphoria Retreat is a lighting design created for a spa in Mystras, Greece. The spa is a four-storey building of 3,000 square metres, carved into the base of a mountain. The lighting of each space was treated as a unique element, supporting a gradual and calming sensory journey. Daylight varies greatly from one space to another, so custom luminaires were designed to imitate daylight conditions. The custom luminaires harmonise the transitions between spaces and enhance the immersive architecture.
