Description

Occupancy this Fall. Bathed in luminous natural light, this exceptional four-bedroom, four-bathroom residence encompasses 3,836 square feet across two coveted corners of the iconic Flatiron Building, with sweeping southern, eastern, and western exposures. Meticulously conceived by Studio Sofield to accommodate both grand-scale entertaining and intimate everyday living, the residence is anchored by its spectacular Great Room, an expansive 40-by-21-foot space crowned by 10-foot ceilings. A striking, custom-curved glass window serves as its architectural focal point, framing captivating south- and west-facing vistas across the cast-iron loft buildings lining the Fifth Avenue Ladies' Mile Historic District-a storied and landmarked stretch of Manhattan renowned for its architectural character and enduring grandeur. A private entry vestibule, finished with hand-clipped marble mosaic flooring and a stone-trimmed portal, offers direct elevator access and an elegant arrival to the residence. The windowed open kitchen is a sophisticated showcase of contemporary craftsmanship, featuring custom millwork by Poliform , streamlined metal flush-panel cabinetry, and state-of-the-art Gaggenau appliances. The serene primary suite is a true retreat, featuring a signature custom-curved window with bright southeastern exposures, a spacious windowed dressing room, and a separate dressing area outfitted with floor-to-ceiling Poliform wardrobe closets. The windowed primary bath is beautifully appointed with high ceilings , separate vanities, a freestanding Studio Sofield-designed soaking tub, and a generous shower with a private water closet enclosed by nickel-framed fluted glass. Additional bedrooms are generously scaled, and each features its own en-suite bath with radiant heated floors, completing this exceptional offering. Unprecedented in new development and thoughtfully integrated throughout each residence is the Ketra ultra-premium lighting system by Lutron, providing fully adjustable light temperature and brightness, along with optional circadian rhythm programming for optimal comfort and wellness. This exceptional residence represents a singular offering within one of New York City's most celebrated architectural landmarks. The Flatiron Building will feature 21st-century amenities designed and appointed by Studio Sofield, including a state-of-the-art wellness center exquisitely conceived with an oversized fitness center and dedicated areas for private training, strength and cardio workouts, a sports simulator and lounge, a 60-foot lap pool, and a cold plunge with adjacent sauna for thermal contrast therapy. Residents may also enjoy views of Madison Square Park and Fifth Avenue from the mezzanine-level Billiards Room and Piano Lounge. Private storage and wine cellars are available for purchase.
