Welcome to Unit B-J at 259 21st Street in Brooklyn—a bright and airy two-bedroom, two-bath condominium located in the former St. John’s School, now known as the St. John’s Condominium. Built in 1904 and transformed into stylish residences in 2004, this boutique building blends historic architecture with contemporary design in one of Brooklyn’s most charming and rapidly growing neighborhoods. As you step into this beautifully appointed home, you’re greeted not by a hallway, but by a private outdoor terrace that stretches the full width of the apartment. It’s an ideal spot to unwind, entertain, or simply enjoy a quiet morning with coffee. Inside, the expansive open-concept living and dining area welcomes you with abundant natural light, high ceilings, and oversized windows—features that reflect the building’s schoolhouse roots and lend an airy, inviting ambiance. The kitchen is fully equipped and ready for a cook of any level. With modern appliances, generous counter space, and thoughtful cabinetry, it functions as both a culinary workspace and a centerpiece for entertaining. The layout of the apartment offers privacy and separation, with the two bedrooms located on opposite ends. The primary suite includes its own en-suite bathroom, while a second full bathroom is conveniently positioned for guests or family use. A private laundry area within the unit adds to the ease of everyday living. The St. John’s Condominium retains much of its original character, evident in the broad hallways and solid construction, but adds modern comforts including elevator access and a live-in superintendent. One of the building’s best-kept secrets is its massive shared roof deck—an expansive space that boasts 360-degree panoramic views across Brooklyn, New York Harbor, and the Manhattan skyline. Located in Greenwood Heights on a peaceful, tree-lined street, the building sits within close reach of bustling 5th and 6th Avenues, where you’ll find local favorites like Sea Witch, Luigi's, Battle Hill and Giuseppina's to name a few. Commuting is a breeze thanks to the nearby R and F/G subway lines and the B63 bus. The home is also zoned for several highly regarded schools, including P.S. 10, Hellenic Classical Charter School, and New Voices School of Academic & Creative Arts, making it a great fit for growing families. Showings are available by appointment only. Don’t miss this rare opportunity to own a piece of Brooklyn history, reimagined for modern living.
