Property Details
Description
This spectacular, one-of-a-kind, authentic open loft with a separate free-standing studio and gigantic private deck is unlike anything else on the market in New York City.
Featuring eight oversized windows facing south and west over Brooklyn's rooftops, this sprawling loft includes a professional-grade kitchen with a commercial Garland stove, custom cabinetry and an impressive dining area that can seat 16. It also has a full bath, a walk-in-closet, three additional full height closets and a sleeping area set off by a partial-height wall backed by more custom shelving and drawers. Ceiling height is over 12 feet throughout.
Follow the interior windowed hallway up a few steps to 600 square feet of roof deck and views in every direction, from Downtown Brooklyn's ever-changing skyline to the iconic Williamsburg Bank Building to the Statue of Liberty and the Verrazano Bridge. In addition to built-in planters, this generous private outdoor space, one of only two in this loft cooperative, is perfect for dining and entertaining or just taking in the sights.
Finally, there's the pièce de résistance: a separate studio loft building with a raw metal roof reaching 13 and a half feet at its peak, windows on facing walls, double industrial-style doors and clerestory windows with original hardware intact. Currently configured with a full-size washer/dryer and utility sink, this unique structure is suitable for entertaining, working, or just about any creative endeavor you can imagine.
Move into this amazing property as-is or design the home of your wildest dreams. Architectural plans exist showing how this property could be adapted to accommodate two to three bedrooms. The possibilities are practically endless.
Set in the heart of vibrant Boerum Hill, 423 Atlantic Avenue, known as the Ex Lax Building, is a well-established cooperative, converted in 1981. The best of Brooklyn surrounds in every direction, including abundant cultural offerings, wonderful eateries, boutiques and artisanal shops and access to almost every subway line. Cats welcome -- sorry, no dogs. First showing by open house, Sunday, September 23rd from 2:30 to 4:30 pm.
