Description

Set in the heart of Boerum Hill in the coveted Ex-Lax building, one of the only industrial loft conversions in the area, this sprawling, pin-drop-quiet architect-designed corner property is what you've been waiting for. To start, this expansive home boasts a 600 square-foot open plan living space with over-sized windows and a kitchen featuring abundant storage, stainless-steel appliances, stone countertops, and a custom crafted steel breakfast bar perfect for quick meals or gazing into the treetops. There's so much to love here especially the dramatic floor-to-ceiling library, which makes full use of the loft's 14-foot ceiling height with a steel-construction mezzanine and custom shelves that span nearly 30 feet. Currently configured with two extra-large bedrooms, the unit could easily be converted to a spacious three bedroom. As is, the primary bedroom has an ensuite bathroom and dressing room and can be set off by a custom-designed glass sliding door for maximum privacy. The second bedroom is gigantic with a walk-in closet of its own. Additionally, the mezzanine level includes desk area and a separate space usable as a sleeping area or home office. The apartment has a full-size washer and dryer and a walk-in storage closet great for bicycles, luggage, and everything else that needs a place. This well-established cooperative converted in 1981 has a gorgeous landscaped common roof deck with skyline views of Brooklyn and Manhattan. The Ex-Lax building also has a resident superintendent, video security, virtual doorman and a central laundry room. It is in close proximity to almost every subway line, including the 2, 3, 4, 5, A, B, C, D, G, N, Q, R, as well as to the Long Island Railroad. Showings by appointment only.
