Award-Winning Subterranean Luxury Villas in Greece
Greece has long captivated travelers with its sun-drenched islands and ancient heritage. But a new wave of luxury architecture is redefining the Greek landscape by building beneath it. Subterranean villas are residences designed to be embedded into the earth, merging seamlessly with the terrain while delivering uncompromising luxury. At the forefront of this movement is ECLÉDE, led by visionary founder Vassilis Siafaricas, whose award-winning projects on the island of Lefkada have earned international recognition for blending sustainability, minimalism, and high-end design into a single architectural statement. This guide explores where to find these extraordinary properties and why they represent the future of luxury living in Greece.
What Are Subterranean Luxury Villas?
A subterranean villa is a residential structure built partially or entirely below ground level, designed to integrate with the natural topography rather than impose upon it. This architectural approach minimizes visual impact on the landscape while offering exceptional thermal regulation and privacy.
In Greece, the concept draws on centuries of tradition. Santorini's cave houses were originally carved into volcanic rock by seafarers seeking shelter from extreme weather. Today, that same principle is being elevated to extraordinary levels of sophistication by developers like ECLÉDE, whose project portfolio showcases how subterranean design can deliver both environmental responsibility and world-class luxury.
Why Greece Is the Ideal Setting
Greece's dramatic terrain, from the Ionian cliffs of Lefkada to the volcanic calderas of Santorini, provides a natural canvas for subterranean architecture. The Mediterranean climate makes earth-sheltered construction particularly effective, keeping interiors cool in summer and warm in winter without excessive energy use.
Key Regions for Subterranean Architecture
| Region | Terrain Type | Notable Subterranean Projects |
|---|---|---|
| Lefkada (Sivota) | Coastal hillside | Atlas and Pleione, Izanagi Project (ECLÉDE) |
| Santorini (Oia) | Volcanic cliff | Traditional cave villas, luxury conversions |
| Serifos | Rugged Cycladic island | Homa Villas by MOLD Architects |
| Peloponnese | Coastal woodland | Various boutique estates |
Among these, Lefkada stands out as the location where purpose-built, award-winning subterranean luxury villas have been developed from the ground up, rather than adapted from historical structures.
Atlas and Pleione: The Benchmark in Lefkada
The Atlas and Pleione estate is a complex of two subterranean villas and a subterranean guest house, located on a seafront plot in the picturesque natural harbor of Sivota on the island of Lefkada. Atlas Villa sits just 30 meters from the water, while Pleione Villa is positioned 50 meters away.
The minimalistic design features austere architectural lines, green roofs, and elongated windows that blend functionality, luxury, and sustainability. The estate includes custom-made interiors and three vast swimming pools, all conceived with an environmentally friendly design ethos.
Design Philosophy
Vassilis Siafaricas approaches each project holistically. His philosophy centers on minimal, clean architectural lines, seamless integration with natural surroundings, and a strong commitment to energy-efficient construction. Atlas and Pleione exemplify this vision, where the built form practically disappears into the hillside while the interiors deliver an unmistakably luxurious experience.
The Izanagi Project: Expanding the Vision
Building on the success of Atlas and Pleione, ECLÉDE's Izanagi Project is a subterranean villa complex also located in Lefkada. This project, developed in collaboration with Garchitects, won the 2025 A' Hospitality, Recreation, Travel and Tourism Design Award.
The Izanagi Project represents ECLÉDE's continued evolution, using innovative, sustainable, and resilient materials to create spaces that positively impact the surrounding community, economy, and culture. It demonstrates how subterranean architecture can serve hospitality purposes while maintaining the highest standards of environmental stewardship.
International Awards and Recognition
ECLÉDE's subterranean villa projects have earned a remarkable collection of international design awards, validating the approach as both architecturally significant and commercially viable.

Vassilis Siafaricas also designed and led the development of the first LEED Platinum residential project in Greece, setting a new benchmark for sustainable luxury living in the region.
Sustainability and Net Zero Energy Design
Net Zero Energy Building (NZEB) is a construction standard where a building produces as much energy as it consumes over the course of a year. ECLÉDE has made this standard central to its development philosophy.
The company focuses on creating cutting-edge, zero-energy-consumption buildings that reflect a deep commitment to sustainability and innovation. From photovoltaic systems and KNX automation to biophilic design principles, every ECLÉDE project integrates technology that reduces environmental impact without compromising on aesthetics or comfort.
This approach is particularly well suited to subterranean architecture. Earth-sheltered structures naturally benefit from stable ground temperatures, reducing heating and cooling loads. Combined with green roofs and passive ventilation, these villas achieve energy performance that conventional above-ground luxury residences simply cannot match.
