A recently completed, meticulous, top-to-bottom renovation defines this approximately 4,100-square-foot full-floor residence at 6 West 20th Streetan owner-quality renovation, executed with meticulous detail and a consistently high level of finish throughout. Nearly 12-foot ceilings, abundant natural light, and private keyed elevator entry establish the scale and presence of a true loft. A central gallery leads to the grand open Great Room, the architectural heart of the home, designed to capture both north and south light for a bright, airy atmosphere throughout the day. Anchoring the space is a Boffi chefs kitchen with matching butlers pantry and a dramatic Arabescato Orobico Grigio marble island, flowing seamlessly into expansive living and dining areas. Handcrafted glass-and-steel casement pocket doors open to the media room, creating flexibility while preserving a striking architectural statement. The secluded primary suite serves as a serene retreat, featuring a substantial walk-in closet and a spa-caliber bath clad in book-matched silver travertine slabs, complete with a stone vanity, deep soaking tub, steam shower, water closet, and radiant heated floors. Three additional bedrooms are complemented by three full bathrooms and a designer powder room with a custom black marble vanity. All full baths are finished in natural stone with Starphire glass enclosures and feature radiant heated floors. Beyond the visible finishes, the renovation prioritized performance and comfort. Newly constructed walls were built with acoustic insulation and sound-attenuating assemblies, creating an unusually quiet and private environment for loft living. Every modern convenience has been integrated, including a museum-quality warm-dim LED lighting plan, Lutron lighting controls and Lutron motorized shades, integrated Sonos-enabled audio, a six-zone central HVAC system with humidity control, and a concealed primary bedroom cinema screen. Additional highlights include 10-inch-wide custom-milled white oak floors, bespoke laundry room millwork, and custom millwork closet build-outs throughout. 6 West 20th Street is a discreet pre-war co-op in the heart of the Flatiron District, moments from Whole Foods, Eataly, and the citys finest dining, shopping, and transit. Pet-friendly and thoughtfully managed, the building combines historic character with modern infrastructure.
