About This Home
HERITAGE COMMERCIAL PROPERTY ON FORTALEZA STREET.
Just steps from Plaza Colon, at the gateway to Old San Juan, this heritage commercial property embodies the city’s historic pulse and cultural vitality. Positioned on the Eastern end of the iconic Fortaleza Street, one of the city’s most bustling thoroughfares, this historic mixed-use building is surrounded by eateries, boutiques and specialty shops, with the city’s main parking garages less than a block away. This stretch of Fortaleza runs adjacent to Plaza Colon, which remains one of San Juan’s most emblematic squares. Historic landmarks like Teatro Tapia and the Antiguo Casino Espanol form the plaza’s perimeter, while a marble statue of Christopher Columbus rises at its center. This storied setting situates the property within the cultural and civic heart of the old city, where heritage and daily life converge.
Floor-to-ceiling glass windows decorate the building’s facade and reveal over 3,000 square feet of open-plan space. Currently curated as an art gallery, the first level of the building features soaring beamed ceilings, modern lighting, and central air conditioning. Sweeping arches lead to a dramatic interior patio and a central atrium that extends vertically through the height of the building. Enclosed in glass, this imposing architectural feature bathes every floor with natural light, while shielding the interiors from direct exposure to the elements. The main stairwell runs parallel to the central atrium, while a secondary stairwell provides direct access to the second and third levels from the street.
A contemporary office space awaits on the second level with five main offices and a generous reception area, as well as a spacious executive suite that doubles as a conference room and opens to an enchanting balcony with views of Fortaleza Street. The third level, which has been brought to shell condition, is a blank canvas awaiting transformation into a private residence, creative studio or additional commercial space. Natural light pours in from the central atrium, while a generous terrace provides additional outdoor space. Above it all, a sweeping rooftop crowns the property, offering privileged city views and the opportunity to develop additional space for entertaining guests or hosting private events.
Offering a rare combination of historic character and functional design, this building stands out as one of Old San Juan’s most versatile mixed-use properties and provides a singular opportunity for investors, entrepreneurs, and visionaries, to steward one of Fortaleza’s defining addresses into its next era.
