A full floor in a 1913 Chelsea loft building designed by architect Walter Haefeli, the brick-and-limestone co-op converted to cooperative ownership in 1977 and known for unusually deep, light-flooded layouts. Residence 11 runs roughly 5,400 square feet across a single level with four exposures, twenty-five windows, and views toward the Empire State Building and Hudson Yards. The renovation is by Matthew Baird Architects, who left the original concrete structure exposed and set a floating walnut floor and a hovering ceiling plane inside it, with interiors by designer Jarlath Mellett.
The result reads as townhouse scale on one floor: a living run stretching past eighty feet, a marble-island kitchen, a primary suite and three further bedroom suites, plus a home office and a conservatory studio.
