Subterranean composition

The hotel, entirely carved into the earth, is located in Imerovigli, the settlement at the highest point of the caldera. It was developed within existing caves with the intention of offering a contemporary interpretation of the traditional cave-dwelling experience.

 

Design Philosophy

The main concept revolves around an organic, shell-like form that flows through the space and shapes the boundaries of the carved structure. This idea is emphasized through the use of a single material across all surfaces, softening transitions and adopting a color palette that echoes the natural stone of the existing caves. At the street entrance, a sharp-angled volume made of perforated masonry directs visitors toward the interior.

 

 

Functional Layout

The ground level is flat, with the volume of the building submerged within the landscape, enhancing its discreet presence. A circular courtyard surrounded by water becomes a focal point, referencing the island’s original name and shape, “Stroggili” (“Round”). Both the courtyard and a structural pillar mark the transition from the ground level to the subterranean areas. A descending staircase, with an intermediate seating landing, leads to a rotating axial door that opens into a 37-meter vaulted sloping corridor.

Ten rooms unfold along one of its long sides, while the opposite side hosts common and service areas, two staircases for vertical circulation, reception, spa, restrooms, an office, preparation spaces, and mechanical rooms. Natural light and air enter the corridor through five skylights in the ceiling, the only visual connection to the sky.

The artificial lighting does not follow a symmetrical axis relative to the vault; instead, it leans toward the room entrances. Repeated 360° light fixtures rhythmically segment the corridor. The room layout retains the traditional tripartite structure found in historic cave dwellings: upon entering, guests encounter the bathroom area, followed by the sleeping zone, and finally the living area.

 

 

Landscape Design & Sustainability

The vaulted form extends beyond the room boundary, creating a sheltered outdoor space with a private jacuzzi and seating for each suite. A monolithic cladding material and deep charcoal tones dominate the envelope, while linear artificial lighting cuts through the rooms, drawing attention toward the dramatic views of the caldera and Oia. The furnishings support a sense of calm and relaxation, with subtle notes of minimal luxury. The spa area follows the same design philosophy, where light reflected on the water surface and the water’s temperature evoke a primordial, womb-like atmosphere. Returning to the upper level, guests encounter individual daybeds, semi-private dining areas, shared lounge spaces, a bar, a pool, and restrooms.

Geothermal systems and advanced insulation methods make the complex bioclimatic, ensuring stable interior temperatures independent of outdoor conditions and achieving a positive environmental footprint.
