Two Seaview Houses for sale in Kea. A rare architectural retreat above the Aegean, designed for those who seek true harmony between nature, privacy and refined simplicity. Set within a peaceful 4,120 m² landscape and inspired by traditional Tziot architecture, the two autonomous bioclimatic residences sit on plots of approximately 1,400 m² each, fully aligned with the natural terrain and offering uninterrupted views of the Aegean. Construction begins in January 2026 and completion is scheduled for the end of 2026. House A, a 43 m² ground-level residence, is shaped as an intimate sanctuary where indoor comfort and outdoor beauty blend naturally. Inside, the open-plan layout unifies the living area, kitchen and bedroom into one warm, cohesive space, with a thoughtfully designed bathroom completing the home. Stepping outdoors, the atmosphere transforms into a serene extension of the interior: a shaded pergola lounge, a spacious terrace facing the vast blue, and a private swimming pool that elevates the experience into something rare and deeply relaxing. The residence is equipped with an energy-efficient heat pump system (cooling, heating, hot water), a water cistern and storage areas, ensuring year-round sustainability and practicality. House B, a 39 m² two-level residence, introduces a vertical interpretation of slow island living, with sea views unfolding at every level. On the upper floor, the open-plan living area with kitchen opens onto a balcony that captures the Aegean in its most unfiltered form, while a discreetly placed WC ensures comfort and functionality. The lower level is dedicated to a serene master bedroom with its own bathroom and direct access to a private veranda featuring a jacuzzi—an intimate retreat designed for complete privacy. Outdoors, a pergola-shaded sitting area provides the perfect setting for relaxed gatherings, quiet mornings or sunset moments. Like House A, the residence includes a high-efficiency heat pump system, water cistern and storage spaces. Both homes enjoy a privileged position in one of Kea’s most authentic and unspoiled settings. Just 500 meters from the sea and surrounded by natural Cycladic beauty, they offer effortless access to crystal-clear waters while maintaining a deep sense of tranquility. The residences are located 4 km from Ozia and 6 km from Spathi, two of the island’s most sought-after spots, offering the perfect balance between privacy and convenience. The location elevates the experience from simple living to a meaningful retreat, ideal for personal use or premium boutique rental. These residences represent a rare opportunity in Kea—a blend of architectural authenticity, bioclimatic design, and an exceptional landscape that invites a slower, more intentional way of living. Two Seaview Houses for sale in Kea. Location Information: Kea is located in the Aegean Sea and it is the nearest inhabited Cycladic island to Athens. It is located just an hour away from the port of Lavrion in Athens. Thanks to its proximity to the capital, Kea Greece (also known as Tzia) is a very popular destination among the locals, especially for weekend getaways and short trips! Even though it is a Cycladic island, it isn’t similar to its Cycladic counterparts. Unlike the rest of the Cyclades islands, it is more verdant. What’s more, instead of the traditional whitewashed Cycladic houses, it is full of traditional farmhouses and tile-roofed buildings in earthy tones. In the inland of Kea Island, you’ll find a lush natural paradise! The island houses rare plant species and wild animals, such as birds and reptiles. For this reason, it makes an excellent destination for nature lovers and exploration aficionados. The capital of the island is Ioulida, a beautiful village which emits a relaxing vibe, thanks to its traditional architecture and car ban! In Ioulida, you’ll find a Medieval castle, a vestige that dates to the Venetian period and the Archaeological Museum among other places of interest. Other beautiful villages include Vourkari, Korissia and Otzias. As for the beaches, some of them are organized, such as Gialiskari, Koundouros and Korissia, while others are secluded and completely unspoiled!
