Plot for sale in Kastella Piraeus, positioned in a quiet residential area within one of the most strategically placed neighborhoods of the city, set between Kastella, Pasalimani (Alexandras Square), and the coastal zone of Votsalakia – Mikrolimano. The property extends to 108 sq.m. and is located within the city plan, offering a fully approved building permit issued in May 2024 by the Piraeus Urban Planning Authority, accompanied by the complete set of architectural and engineering studies, allowing for immediate development. The approved permit is for the construction of a five-storey residential building on pilotis with a basement, presenting a fully structured and ready-to-execute development opportunity in an area with consistent residential demand and strong long-term value. The project includes three full-floor apartments of approximately 55 sq.m. each, along with a duplex residence on the 4th and 5th floors, with a total internal area of 80 sq.m., distributed as 45 sq.m. on the 4th floor and 35 sq.m. on the 5th floor. The basement level is designed to accommodate four storage units of 5 sq.m. each, enhancing the practicality and overall functionality of the development. In terms of parking, two spaces have already been legally secured and registered with the Land Registry within the pilotis. One is designated for the duplex, while the second will be allocated to one of the apartments, most likely the 3rd floor unit. In addition, the duplex benefits from the potential use of an extra pilotis space as a second parking position, a feature that significantly increases its overall appeal and market value. For the remaining two apartments, the required parking contributions have already been paid to the Municipality of Piraeus, ensuring full compliance with urban planning regulations and eliminating future obligations for the developer. The plot is fully prepared for the commencement of excavation works and subsequent structural construction. Notably, in August 2025, stabilization and restoration works were carried out on the adjacent building walls, including plastering and reinforcement mesh installation, further reducing technical risk at the construction stage. The location itself is a key asset. Within walking distance, there is access to metro transportation, retail amenities, and the University of Piraeus, making the development suitable for both end-users and investment purposes. From the 3rd floor and above, the residences will enjoy sea views, a defining characteristic that elevates the final product and differentiates it within the local market. This is a rare opportunity to acquire a fully prepared development plot in Piraeus, with an active building permit, resolved planning parameters, and a location that combines residential calm with direct proximity to the city center and the sea, offering both immediate usability and strong future returns.
