175 5Th Ave

Completed in 1902 and rising 24 stories, this landmarked Beaux‑Arts tower has been converted into full‑floor and large multi‑bedroom condominiums that retain the building’s historic geometry and presence along Fifth Avenue and Madison Square Park. Residences range from three- to seven-bedroom plans, many formed by combining units to create expansive floor plates with private elevator vestibules, oversized acoustically rated windows, and exceptionally high ceilings. Interior finishes reflect a studio‑led restoration approach that pairs archival materials with contemporary systems: Poliform millwork and wardrobe systems, Gaggenau appliance suites, radiant‑heated bathroom floors, and integrated Lutron Ketra lighting are standard in many homes. Signature architectural moments — curved corner windows, great rooms of dramatic scale, and windowed primary baths with bespoke soaking tubs — define the living spaces. The building’s amenity collection, designed by Studio Sofield, centers on wellness and recreation with an oversized fitness center, private training areas, a sports simulator and lounge, a 60‑foot lap pool, cold plunge and sauna, plus mezzanine communal rooms overlooking Madison Square Park. Private storage and optional wine cellars are available; select units include private outdoor terraces of varying sizes. The conversion emphasizes privacy, generous closet and dressing areas, service and utility rooms, and contemporary mechanical upgrades while preserving the Flatiron’s historic exterior character and its central Manhattan location.
