Discover an investment opportunity located at the edge of Athens' historic center. With views of the Acropolis from four apartments and a short walk to all major historic landmarks, this development is nestled in the rapidly emerging post-industrial urban culture of Gazi and Keramikos. These neighborhoods are the new epicenters of modern living and investment, offering vibrant nightlife, cultural attractions, and convenient transportation options. Only 150m away from the Keramikos metro station, this property provides direct links to the airport and a short ride to the port of Pireas. This project will become the first Passive (autonomous energy/zero OPEX cost) building in central Athens, and comes up for sale in the form of a construction shell of six floors plus a penthouse (doma), totaling 531m² and up to nine potential flats. Combining functionality, sustainability, and aesthetics, it is fully certified by the Hellenic Passive House Institute. The green design ensures a sustainable living environment, perfectly aligned with contemporary eco-friendly standards, meeting the demands of modern, environmentally conscious residents. Offering flexible investment opportunities, this project allows for the sale of individual apartments or conversion into a luxury apartment hotel. According to a detailed business plan, the latter option could yield returns exceeding 12%. This versatility, coupled with the prime central location and innovative design, makes it an attractive prospect for a diverse range of investors.
