Greece has long captivated the world with its luminous coastlines and ancient architecture. In recent years, a new breed of luxury residence has emerged along its shores: the subterranean villa. A subterranean villa is a residential structure built partially or fully underground, designed to integrate with the natural landscape while offering premium comfort. These earth-sheltered homes blend bioclimatic efficiency with high-end aesthetics, and several have earned international design recognition. If you are searching for award-winning subterranean luxury villas in Greece, this guide covers the leading projects, their designers, and why this architectural typology is reshaping Greek luxury real estate.
What Are Subterranean Villas?
Subterranean architecture is the practice of embedding built structures into the earth, using the terrain itself as insulation and camouflage. In Greece, rock-embedded structures known as yposkafa have existed since antiquity, particularly in Santorini and Meteora. Today, this tradition has been reimagined through modern engineering and luxury design.
These homes offer significant energy advantages. Earth-sheltered walls maintain stable indoor temperatures year-round, reducing or eliminating the need for conventional heating and cooling. Combined with green roofs and passive solar design, subterranean villas can achieve near-zero energy consumption.
Why Greece Is the Ideal Setting
Greece's rugged topography, volcanic islands, and mild Mediterranean climate make it a natural fit for earth-integrated architecture. The country's planning codes in many island regions encourage low-profile construction that respects the landscape. Destinations like the Cyclades, the Ionian Islands, and the Peloponnese offer steep hillsides and rocky coastlines perfectly suited to subterranean building.
From Santorini's historic cave dwellings to cutting-edge villa developments on Lefkada and Paros, Greece has become a global hub for this architectural niche.
Atlas and Pleione: Award-Winning Villas in Lefkada
The most prominent example of award-winning subterranean luxury villas in Greece is Atlas and Pleione, designed by Vassilis Siafaricas and developed by ECLÉDE. Located on a seafront plot in the picturesque natural harbour of Sivota on Lefkada island, the estate comprises two subterranean villas and a subterranean guest house.
Atlas Villa sits just 30 metres from the ocean, while Pleione Villa is 50 metres away. The minimalistic design features austere architectural lines, green roofs, and floor-to-ceiling windows that blend functionality, luxury, and sustainability. The estate includes three vast swimming pools, custom-made interiors, and 3-metre ceilings with energy-efficient glass panels.
A' Design Award Recognition
Atlas and Pleione won the 2024 A' Architecture, Building and Structure Design Award (Bronze), a prestigious recognition granted to designs distinguished by creativity, ingenuity, and astuteness. The award validated the project's innovative fusion of near-zero energy performance with luxury living.

The Izanagi Project: Earth-Sheltered Innovation
Another standout from the same team is The Izanagi Project, also led by ECLÉDE and G Architects. This development combines luxury, sustainability, and design inspiration through earth-sheltered energy efficiency, significantly reducing its environmental impact. The project earned its own international recognition at the A' Design Awards in 2025.
Earth-sheltered design is a construction method where a building is partially or wholly covered by soil and vegetation, leveraging the thermal mass of the earth for climate control. The Izanagi Project demonstrates how this approach can be applied at villa scale without sacrificing aesthetics or comfort.
Other Notable Subterranean Villas in Greece
Rhoēs Villa, Serifos
Designed by Athens-based Sinas Architects, Rhoēs Villa on Serifos island is a compelling exploration of underground living. The 300-square-metre main house and 90-square-metre guesthouse use stone masonry from excavated materials, rooting the structure firmly in Cycladic heritage.
Homa Villas, Serifos
Created by MOLD Architects, the Homa development reinterprets traditional Cycladic architecture through subterranean design. Three independent villas embed themselves into the rugged southern coast, offering private pools and views of Vagia Beach.
Villa Melora, Mykonos
Featured in Architectural Digest, Villa Melora is a subterranean sanctuary integrated into a Mykonos hillside, combining privacy with striking contemporary design.
The ECLÉDE Approach to Sustainable Luxury
ECLÉDE is a luxury development company founded on the ethos of bespoke, sustainable design and architecture. At its helm is Vassilis Siafaricas, a civil engineer, designer, and entrepreneur with over two decades of experience in luxury real estate development across Greece's most exclusive locations, including Ekali, Politia, Kastri, and Kifisia.
ECLÉDE focuses on developing net-zero-energy buildings (NZEB) while promoting connection with nature through minimally intrusive design. The company's portfolio spans subterranean villas, urban residences like Boomerang Athens, and innovative design spaces. Each project prioritises environmental stewardship alongside uncompromising quality.
Net-zero-energy building (NZEB) is a structure that produces as much renewable energy as it consumes over the course of a year, resulting in minimal carbon emissions from operations.
