Description
Welcome home to 40 East 21st Street. A key-locked elevator opens directly into this expansive floor-through loft, which is updated yet retains authentic details such as exposed brick, 12' high beamed ceilings and massive tilt and turn windows. Defining features of this pre-war home include 43 feet of contiguous living and dining space, a 22 ft wide front living room and a massive built in banquette along the perimeter of the north side of the loft, which overlooks the trees of landmarked East 21st Street. Configured as a two bedroom / two bath with one of the bedrooms being interior, one can easily add a third bedroom in the front living area which would result in a two bedroom plus a large home office. The oversized chef's kitchen has an island, custom cabinetry, a large pantry for storage and is open to the dining area, which can accommodate seating for 12. The primary suite is generous in size measuring 17'x14', and there is a huge walk-in closet plus a windowed en-suite bathroom. Adjacent to the primary suite is a large second bedroom or home office/guest suite with a full bathroom. Rounding out the loft is nearly 20 linear feet of closets and a side by side full-size washer / dryer. Other features include central a/c, a large private storage locker in the cellar and super low monthly fees. 40 East 21st Street is an 11 story pre-war cooperative with 10 residential units. This highly coveted and incredibly convenient location is moments from Gramercy Park and Madison Square Park and just a few blocks from Union Square, offering easy access to Flatiron, Nomad, Gramercy and the Village. Some of downtown's best restaurants are within a few blocks and public transportation is accessible in every direction.
