Description
205 Dekalb is a 22-foot-wide brownstone that has been beautifully renovated in the absolute sweet spot of Fort Greene. With soaring 12 ft ceilings on the parlor floor, central air throughout, and a 55-foot garden extension, this home delivers the ultimate Brooklyn combination: an expansive, light-drenched owner’s triplex with incredible rental income or a flex guest space. Enter on the parlor floor and you immediately feel the generous proportions. The wall along the staircase has been opened up, creating a super lofty feel and a stunning sense of volume from front to back. Facing south, the living room is bathed in hours of afternoon sun, grounded by preserved crown moldings, exposed brick, and gorgeous herringbone and wide-plank wood floors. The open kitchen is fully equipped with sleek Caesarstone countertops and a suite of Bosch appliances, looking straight out onto your large private deck and tranquil garden for effortless indoor-outdoor flow. Up on the second floor, you’ll find a fantastic layout anchored by a generous family room and den—the ideal place to hang and unwind separate from the main living room. The rear of this floor is dedicated to the primary suite, a quiet sanctuary overlooking lush green treetops. It features a walk-in closet and a windowed en-suite bath with a double vanity. A second full bathroom and a dedicated laundry room on this level make everyday routines completely seamless. The top floor is bathed in sunlight, highlighted by character-rich exposed white painted brick and three bright bedrooms. There are 3 bedrooms up here with one full-width bedroom with its own en-suite bath, fantastic walk-in closets, and a two more bedrooms down the hall. Down on the garden level, the building was extended nearly 60 feet deep. This thoughtful footprint allows for two high-income-producing apartments, or gives you the freedom to keep the studio as a private in-law/guest suite or dedicated home office. Beneath it all, the partially finished basement offers tons of extra square footage with plenty of room to easily set up a home gym, kids' playroom, and all the storage you could ever need. Outside, you’re just two quick blocks to Fort Greene Park for morning runs, farmers market Saturdays, and tennis, with neighborhood favorites like Roman’s, Sailor, and Walter’s right around the corner. An extraordinary 22-foot-wide package with space, light, and unbeatable flexibility.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
