Description

Exquisitely renovated home in a historical landmarked townhouse, located in the heart of the Flatiron District, awaits the most discerning buyer. This stunning floor-thru living/workspace, accessed by two flights up, was thoughtfully and impeccably redesigned from top to bottom. Currently configured as a spacious 2-bedroom with a large open living, dining and work area, this home can easily be converted to have a proper work-from-home office or 3rd bedroom with minimal change to the existing living space and flow (see alternate floorplan). The apartment spans almost 60 feet north to south with soaring 12-foot ceilings and gorgeous extra wide plank Dinesen Douglas Fir flooring throughout, giving the home a distinctly minimal, yet organic aesthetic. At the heart of the home is the sophisticated bespoke 18-ft long Bulthaup kitchen - the perfect marriage of form and function, equipped with a full suite of Miele appliances, including a washer/dryer discreetly tucked within the vast wall of custom millwork cabinetry, providing ample storage. The kitchen flows seamlessly into the grand living and dining area complete with a decorative fireplace, boasting an original marble mantel and oversized windows allowing for maximum light. Each of the bedrooms is outfitted with floor-to-ceiling custom-designed closets and tall windows to let in sunshine throughout the day. There are two full bathrooms tastefully renovated with Duravit fixtures; the main bathroom features a large stall shower, radiant heating and a custom granite slab floor and the 2nd bath has a bathtub and is conveniently located next to the potential 3rd BR. Other luxurious details include a new central HVAC system with a Nest Thermostat, floor-to-ceiling custom millwork for all closets and cabinetry, and abundant light through both Northern and Southern exposures. Built in 1846, 28 East 21st Street is a landmark twenty-five ft wide Italianate townhouse that once served as the home for renowned architect, Richard Morris Hunt, and The Society of Decorative Arts. This friendly and flexible self-managed coop has only 6-units, including a live-in super. Zoned for PS 340, and situated at the crossroads of Chelsea, Gramercy, Union Square, and Madison Square Park, this Flatiron District coop is amidst the best restaurants and shopping that the city has to offer and is conveniently located just blocks from all major subway lines at both 23rd St and Union Square.
