    What's special

    Welcome to Residence 3H — a soulful loft within the historic Ex-Lax Building, where original warehouse character meets endless creative possibility in the heart of Boerum Hill. Offered for the first time, this is a rare opportunity to create a truly sui generis home — deeply personal and entirely your own. Loft lovers will immediately appreciate the remarkable scale, volume, and authenticity of the space: nearly 13-foot ceilings, five oversized south-facing windows perched at tree level, and an expansive open layout bathed in natural light throughout the day. Raw, honest, and unmistakably New York, this is the kind of home that sparks imagination. The proportions are generous, the atmosphere cinematic, and the potential extraordinary. For those with a creative spirit and an eye for design, this is not simply an opportunity to purchase a home, but to create and shape one. Originally constructed in the 1920s and thoughtfully converted to a cooperative in 1981, the Ex-Lax Building remains one of Brooklyn’s most distinctive loft residences. Residents enjoy a full suite of conveniences including elevator access, central laundry, updated intercom system, live-in superintendent, and a spectacular common roof deck with sweeping views of Downtown Brooklyn. Perfectly positioned at the nexus of some of Brooklyn’s most vibrant neighborhoods, Boerum Hill offers unparalleled access to the very best of city living. Moments away are celebrated cultural institutions including BAM, the Brooklyn Museum, and Barclays Center, alongside beloved cafés, acclaimed restaurants, boutique shopping, and everyday conveniences such as Trader Joe’s, Whole Foods Market, and Public Records. Fort Greene Park is also within easy reach. Transportation is exceptional, with seamless access to the A/C/G/2/3/4/5/B/D/N/Q/R subway lines, connecting you effortlessly to the rest of the city. A rare offering defined by scale, history, flexibility, and soul — Residence 3H is ready to become your vision.
