If you're looking for a truly unique example of subterranean splendor, indulge yourself in this new residential development in Andros, the second-largest island of the Cyclades.

Nestled among Andros' wild mountains, fecund valleys and waterfalls, this complex consists of two detached houses covering around 600m2 in land of 9200m2. “Residence A” consists of a living/dining room, kitchen, bathroom, two bedrooms with sea views, a subterranean master bedroom and an independent guesthouse on a lower level. A stairway links organically the residence to an existing natural stone cave.

“Residence B” consists of a living /dining room, kitchen, bathroom, one bedroom with sea view and two subterranean “en-suite” bedrooms, accessible through an interior atrium. This house also has an independent guesthouse on a lower level. Both houses have a basement and swimming pool.

Modern and rigorous, the design bears clear lines and is organically linked to the natural landscape of Andros. The commitment to fully integrate with the surrounding area, as well as the need to maximize the utilization of the plot's seamless view due to the land's topography and position, lead the design team to the creation of open (airy) spaces with large openings without columns or walls. The roof of the dwelling is made of two flat concrete slabs, which are treated as green–roofs of local and Mediterranean vegetation providing a thermal shield to the house and assist further in the integration of the new building with its environment. As a result, the properties offer high-end aesthetic, privacy and breathtaking vistas over the endless blue.

The underground abode features smart examples of energy-efficient architecture such as geothermal heating and passive design that keep the interior comfortable while minimizing the need for heating or cooling in the winter and summer months. The green roofs are an integral part of this climate-proof, forward thinking construction in this beautiful Cycladic wild environment.
