105 5Th Ave

The Folio House at 105 Fifth Avenue is an 11-story Beaux-Arts cooperative completed in 1880 and converted to residences in the late 20th century. The boutique property contains a small collection of sizable loft-style units characterized by high ceilings (commonly 11–12 feet), oversized arched and floor-to-ceiling windows, exposed historic columns and pre-war architectural detailing. Unit types range from one- and two-bedroom lofts to expansive corner collector residences created by combining units; many homes feature open-plan living/dining spaces, walk-in closets, pantries, eat-in or chef-caliber kitchens, and generous storage including private cages. Building services and systems include a virtual doorman, two passenger elevators plus a freight elevator, full-time superintendent and porter, package room, private storage bins, bike storage, and recent hallway and amenity renovations. Shared amenities listed across offerings include a roof deck, card-operated laundry room, and a newly renovated gym; the co-op permits in-unit washers and dryers with board approval and allows pets. Located at the corner of Fifth Avenue and 18th Street in the Flatiron/Ladies Mile corridor, the property sits between Union Square and Madison Square Park and is steps from multiple subway lines, grocery options (Whole Foods, Eataly), restaurants, shopping and the Union Square Greenmarket, offering classic pre-war loft living with modern systems and neighborhood convenience.
