Description

The opportunity you've been looking for! Own an entire multifamily townhouse on an exquisite, tree-lined block in Brooklyn's beloved Boerum Hill neighborhood. 46 St. Marks Place is a rare chance to plant roots in one of Brooklyn's most sought-after neighborhoods, where you can hop on the subway at Atlantic Terminal, catch a show at Barclays Center, spend weekends strolling through Prospect Park, and dine at local favorites like Grand Army, French Louie, and Rucola.

This Brooklyn gem retains the original charm and details that make New York City brownstones truly special, with crown molding, classic millwork, decorative fireplaces, and the high-quality craftsmanship of a home built to stand the test of time. Featuring three spacious full-floor, free market apartment homes with dedicated entries and separate utilities, each carries their own distinct character throughout.

The owner's duplex is a stunning two-bedroom, two-bathroom home with two additional office / den spaces that span the first and second floors of the building. On the garden level of the duplex, you'll find an expansive bedroom with plush carpeting and enough room for a bed, desk, even a couch and TV, making it an enviable hangout space. This level also features a full bath, a private office, a utility room with a washer / dryer and ample space for storage. A long hallway serves as a versatile flex area for additional desk space or home gym. On the main level of the duplex you'll be greeted by a picturesque dining room for entertaining, that flows into a cozy living room alongside a second full bath and bedroom with generous closets and a decorative fireplace. The spacious kitchen leads to a walk-out elevated deck where you can enjoy your morning coffee while overlooking a beautifully landscaped private backyard that's entirely yours - a true sanctuary in the heart of the city!

The second floor is an elegant three-bedroom, one-bath home with soaring ceilings, oversized windows, and a sun-drenched living room overlooking the rear yard. There are original details at every turn, with a dedicated dining area off the kitchen. This floor features a superb primary bedroom with an original decorative fireplace, large closets, and a layout roomy enough for a bed, desk, and additional seating. The second and third bedrooms can serve as a guest room, office, or nursery.

Finally, on the top floor is a generous four-bedroom, one-bath home that boasts a light-filled living room and sweeping views of the Boerum Hill treetops and the Downtown Brooklyn skyline, with enough room to spread out and space to come together.

46 St. Marks Place is move-in ready and sold as-is. Bring your own personal touch, or move right in without making any changes. Currently fully occupied, the main level duplex will be delivered vacant at closing, giving you the ability to live in and own an iconic Brooklyn townhouse while the upper two apartment homes generate rental income from day one.

Showings by appointment only. Please contact the listing agent directly for scheduling, floor plans, and any additional information.
