Entry to the Dolphin spa in Santorini is through a courtyard. Although facing towards the caldera on its narrow side, its door makes it a rather introverted area. Placing a pergola above this outdoor lounge area protects from the strong sun and ensures privacy for guests. Within the spa itself, the largest interior space is reserved for a Jacuzzi which extending to the walls, mirrors the vault of the room. All interior spaces are excavated in the ground and feature an organic geometry. Stepping stones allow access to the treatment room on the back. The architectural approach is barren and monolithic, a return to primordial sensations.
