In the heart of Exarchia, in one of the most vibrant and historically rich areas of Athens, an exceptional standalone office building of 1,250 sqm is presented for lease, extending across five levels. The core structure dates back to 1900, with an additional floor added in 1930, and the property has been officially classified as a listed and protected monument, representing a rare piece of the city’s architectural heritage. A meticulous and complete reconstruction has recently been carried out, faithfully restoring and showcasing the building’s remarkable decorative and architectural elements. Original ceiling frescoes, ornate wall details, traditional tiles and craftsmanship from another era have been preserved in their entirety, blending classical elegance with modern comfort. At the same time, every auxiliary area has been efficiently utilized and the building has been fully equipped with contemporary infrastructure: advanced fan coil heating–cooling systems, alarm installation, high-spec cabling and networks, fire safety system, security cameras and all necessary technical provisions required for the seamless operation of a modern professional environment. The property features two entrances, two staircases, a large elevator and a welcoming reception area on the ground floor, offering great flexibility in its layout and potential uses. Its location is truly privileged, situated next to museums, the National Technical University, Exarchia Square and major road arteries. It lies just 10 minutes from Omonia and 20 minutes from Kolonaki and Syntagma, ensuring excellent accessibility and connectivity. This is a rare opportunity and an ideal choice for hosting corporate headquarters, offices, a gallery, cultural venue or museum space, combining historical significance, architectural beauty, modern technological infrastructure and a premium urban location.
