For sale is an exceptional three-storey seafront corner building of approximately 426 sq.m., located in one of the most privileged coastal areas of Piraeus, on Akti Moutsopoulou. Built in the 1930s and fully renovated in 2007, the property preserves the distinctive character of its era, offering high ceilings, large openings and abundant natural light, while enjoying uninterrupted sea views from its main façades. The building comprises the entire first floor, the entire second floor, as well as the rooftop level (80 sqm). Each of the two principal floors (170 sqm each) features a generous layout with three bedrooms, two bathrooms, a separate kitchen and a large living–dining area opening onto sea-facing balconies. Due to the comfortable floorplan and the thoughtful arrangement of interior spaces, each level can be divided very easily into two completely independent apartments. As a result, the building has the potential to accommodate up to five residential units in total, including the rooftop suite. This offers significant flexibility and multiple development scenarios, ranging from a single luxury residence to separate apartments or smaller investment units. Above the main floors lies the rooftop level, which includes an enclosed room with its own bathroom, along with the exclusive use of approximately 100 sq.m. of open terrace. This rare outdoor area offers the opportunity to create a premium penthouse, a rooftop lounge or a landscaped terrace with exceptional panoramic views along the coastline. Although the building does not currently include an elevator, the existing structure allows for the installation of one with appropriate architectural modifications. The property is not listed as preserved, providing freedom for redesign or redevelopment according to the buyer’s vision. It was leased from 2007 to 2013 and has remained closed since then, meaning that refurbishment or upgrading will be required to meet modern standards or any new intended use. The ground-floor commercial store is not included in the sale; the offer concerns exclusively the first and second floors as well as the rooftop level. With its unique seafront setting, corner orientation, generous interior spaces, the ability to create five independent residential units and its exceptional terrace, this property represents an outstanding opportunity for the development of a high-end private residence, boutique hospitality project, premium serviced apartments or elegant commercial offices.
