Boasting 16-foot ceilings and monumental windows overlooking Union Square Park, Residence 3A at 15 Union Square West is a pristine two-bedroom, two-and-a-half bathroom home with both remarkable volume and finishes. At nearly 2,200 square feet, the space is divided neatly with the bedrooms, each with an en-suite bathroom, separated from the grand public spaces.

Enter the home through a proper foyer with an adjacent coat closet and elegant powder room. The gallery leads to the great room, the centerpiece of the home. The sheer volume of space is unmatched, and eastern light floods the home through the 16-foot windows. The building’s original 19th century archways have been preserved and restored, and behind them a wall of glass overlooks Union Square. Opposite, custom built-in bookshelves stretch to the ceiling, a library in the living room. With no shortage of space, the room can accommodate dozens for living, dining and entertaining.

The open kitchen features marble countertops and top-of-the line appliances from Miele, Viking and Sub-Zero. This includes a built-in Miele coffee machine and a Sub-Zero wine refrigerator. The lime-colored lacquer cabinets and finishes create a pleasant contrast to the Mahogany oak floors and offer ample storage.

The principal bedroom suite is large and inviting. There are two closets, including a walk-in closet with custom shelving. Soft and tranquil, the en-suite bathroom is covered with rose quartz flooring, countertops and wall paneling. There is a large shower, and oversized vanity, and additional open shelving for storage.

The second bedroom, currently used as a home office, is painted a vibrant red. A wall of custom closets were added, for a total of 7 closets. A true suite, there is an en-suite bathroom here as well.

Residence 3A includes a semi-private outdoor space shared only with one other unit; each has its own parcel.

Additional features and details help make this an exceptional home. There is a washer/dryer next to the bedroom suites; electronic blackout shades in the living room; and Crestron lighting.
