Suspended above one of Puerto Rico’s most culturally significant landmarks, The Legacy Loft is a rare offering: the entire fifth floor of the historic El Mundo Building, built in 1923 by architect Francisco Roldán for the famed El Mundo newspaper. This 2,800+ sq ft open-plan space with 12-foot ceilings and 15 oversized, bay-facing windows offers panoramic views over San Juan Bay and the Harbor—unmatched in Old San Juan. A blank slate ideal for a luxury residence or creative conversion, the layout is entirely column-free, with extraordinary light and volume. The building, listed on the National Register of Historic Places, is a masterwork of early 20th-century architecture, blending Chicago Style structure with Art Deco, Spanish Revival, and Moorish motifs including glazed ceramic wainscoting and mosaic tile arches. Now reconfigured into seven mixed-use units—including residential, commercial, and office—few spaces remain with direct water views. Formerly a prestigious law office, this fifth-floor unit is one of the last opportunities to custom-design a residence within a landmark building. Features include an elevator—rare in Old San Juan—and a tranquil location facing Bastión de las Palmas, a quiet, tree-lined plaza with only foot traffic. Steps from galleries, dining, and historic landmarks, this is heritage living at its most iconic.
