815 Willoughby Avenue -  Two Units - 4 Stories - 3,000 SF - Lot: 18.75' x 100' - Taxes: $4,428/yr CONTRACT SIGNED. Bring Your Contractor - A Rare Brownstone Opportunity Step back in time as you enter this stately, south-facing brownstone, built circa 1899. Every detail recalls an era when craftsmanship mattered-rare woods, intricate plasterwork, and hand-carved stone. The grand parlor level welcomes you through double wood doors, where soaring ceilings, wainscoting, crown moldings, and the original amber-hued light fixture set the tone. Two dramatic floor-to-ceiling windows flood the parlor with light, framing a magnificent gas fireplace adorned with beveled mirrors and intricate carvings-the centerpiece of gatherings past and those still to come. Throughout the home, you'll find seven fireplaces, each with its own character, and a collection of 9-foot doors, including elegant pocket doors dividing the parlor rooms. On the garden level, etched-glass doors open into a warm, wood-paneled interior. A built-in bar framed by an arched entry and abundant storage evoke a timeless charm, while the eat-in kitchen overlooks a private, north-facing backyard awaiting transformation. The upper duplex continues the story-original closets, wood shutters, and four additional fireplaces make each room distinct. An alcove room with built-ins and a stone fireplace offers flexible use, while the separate windowed kitchen and bath bring convenience and privacy. A beautifully carved staircase with curved handrails and spindles ties it all together. This home is ready for a vision, whether as a grand single-family residence or a reimagined two-family dwelling... and is a once-in-a-generation opportunity to restore a true Brooklyn brownstone to its full glory.  Neighborhood Highlights: Just blocks from dining and nightlife favorites like Mao Mao Thai, Little Mo, The Concrete Jungle, and Ornithology Jazz Club. Daily conveniences are nearby at Food Bazaar, MG Pharmacy, and Benjamin Moore Hardware. Easy access to the J/M/Z trains at Myrtle Avenue, multiple bus lines, and CitiBike makes for seamless commuting.
