This single tenant building sits within one of Manhattan’s most coveted Upper East Side corridors, located just off Madison Avenue and a half-block from Central Park. Situated in the heart of the Upper East Side’s Gold Coast, 26 East 78th Street presents a rare leasing opportunity for gallery, nonprofit, foundation, and cultural users. Fully restored in 2025, the turn-key townhouse offers classic Upper East Side character with modern architectural execution. A dramatic entry lobby with 20-foot double-height ceilings establishes a museum quality arrival, complemented by a sculptural internal staircase and a full-building-width glass elevator. Interiors are defined by scale, light, and flexibility, supporting a range of institutional and exhibition driven uses. The address benefits from exceptional walkability, positioned between the cultural draw of Fifth Avenue museums and the upscale shopping destination of Madison Avenue. Its proximity to Central Park enhances visibility and lends prestige to any commercial or professional presence. The surrounding area blends affluent residential density with strong daytime foot traffic driven by tourists, neighborhood residents, and boutique retail patrons.
