Newly built, semi-underground villa with unobstructed sea view and pool, 170 sq.m., with an additional building capacity of 35 sq.m. The residence includes a total of 170 sq.m., 3 bathrooms, 1 W/C, and 2 open-plan living room–kitchen areas. Outdoors, there are 2 swimming pools overlooking the Aegean Sea. The ultimate living experience, where architecture is perfectly harmonized with the natural landscape, offering a unique sense of serenity, privacy, and refined aesthetics. The underground (semi-subterranean) houses offer a wide range of advantages, such as energy efficiency and natural thermal insulation, maintaining a stable temperature throughout the year thanks to the thermal mass of the earth. This ensures natural cooling during summer and warmth in winter, with low heating/cooling costs. They offer reduced energy losses, a high level of soundproofing from external noise, aesthetic integration with the environment, and long-lasting durability. A key advantage is their high resistance to extreme weather conditions (strong winds, intense temperatures, earthquakes, wildfires), while also offering significant investment value due to their comparison with “classic” constructions and the “exclusive property” status they provide. The property is located in a privileged spot with open views and easy access, just a few minutes from the beach and 10 minutes from the town of Karystos and all essential infrastructure, and only 1.5 hours from the port of Rafina.
