Design innovation

The construction of this undercut residence, nestled in the rugged landscape of Santorini, presented significant challenges. However, the project successfully overcame these obstacles, showcasing both architectural and structural excellence.

 

Exterior Shell

The design faced numerous challenges, including unsafe, underground tunnels, landslides, a deteriorated underground pocket and soil decay. Through meticulous geotechnical analysis and innovative design, the building exemplifies resilience and ingenuity. Central to the project’s success is its core materiality, where reinforced concrete is used to create a strong shell. The design ingeniously incorporates two retaining walls that support 600 cubic meters of infill, while a third arched wall, extending 6.5 meters inward, acts as a backbone, dividing the space into distinct sections. A dome unifies the ceilings across these sections.

 

Functional Organization

The façade is characterized by three semi-open spaces, each defining a distinct aspect of the building’s exterior. The first space features a flat, modern roof that leads to the swimming pool. The second space, with its vaulted design, reflects local traditions and marks the main entrance. The third space represents a contemporary architectural experiment: an acute-angled dome, known locally in Santorini as the “double-cube,” vertically intersects a semi-circular dome, creating a unique architectural element.

The residence’s interior features two en-suite bedrooms situated at the back, while the front area comprises the kitchen and living room. Given that underground spaces typically have a single source of light and ventilation, the design includes inverted arches as dividers -originally segments of the cross-vault intersection- serving as striking architectural elements as well as light conduits that enhance privacy and eliminate the need for conventional doors.

 

Light & Materiality

Artificial lighting is subtly integrated into the partitions to enhance the minimalist aesthetic, leaving the ceiling bare and uncluttered. As the sun sets, casting kaleidoscopic hues across the western sky, the interior of the house transforms. The walls take on delicate shades of pale pink, blue, and amethyst, as if imbued with the essence of twilight. Despite the challenges faced during its construction, this undercut house stands as a prime example of design innovation and perseverance, offering a stunning retreat that embraces the breathtaking views of Santorini.
