This distinguished landmarked 21 ft. wide Neo-Grec brownstone has been lovingly maintained and thoughtfully upgraded by its current owners for more than two decades. Well-positioned on one of Park Slope's most coveted blocks between Prospect Park West and Eighth Avenue, close to Grand Army Plaza and Prospect Park, this legal four-family townhouse is currently configured as a three-family home, offering an ideal balance of luxurious owner occupancy and strong income potential.

The owners' residence occupies the garden and parlor levels in a beautifully appointed 2-bedroom, 2.5-bath duplex , where thoughtful renovations complement the home's extraordinary nineteenth-century craftsmanship. Mitsubishi & LG mini-split systems provide efficient heating and cooling, while all-new Marvin windows installed throughout the townhouse between 2014 and 2015 enhance comfort and performance while preserving the residence's historic character. Soaring ceilings and graciously proportioned rooms showcase a remarkable collection of original details. The parlor level retains its magnificent mahogany staircase, richly detailed mahogany moldings and window casings, elegant wainscoting, window shutters, pocket doors and original dining room mantel, all preserved in exceptional condition. Upstairs, finely crafted oak millwork continues the home's architectural story, reflecting the quality and artistry of its original construction.

The parlor-level kitchen opens to a beautifully designed outdoor retreat, featuring a custom steel & Ipe wood deck installed in 2016 with a staircase leading directly to the backyard. Designed as a private urban sanctuary, the garden features a tranquil Zen-inspired landscape with bamboo fencing, bluestone pavers, and custom terracotta tile details, creating a serene extension of the living space perfect for entertaining, gardening, or quiet moments outdoors.

Below the duplex, a fully finished lower level reveals an extraordinary surprise: a custom retro-inspired movie theater designed by the previous owner, Theo Kalomirakis, widely regarded as the father of luxury home theater design. This remarkable screening room served as the prototype for what would become his internationally acclaimed work and remains a truly unique amenity for film enthusiasts and entertainers alike.

The upper floors are configured as two oversized one-bedroom, one-bath apartments , each thoughtfully designed with an additional home office or nursery. These generously scaled apartments offer excellent rental income potential while maintaining a high standard of comfort and livability. The top-floor residence is currently leased until April 2027 , providing a stable income stream for the next owner.

Located within the coveted P.S. 321 school district , 894 Union Street enjoys one of Brooklyn's premier residential locations, just moments from Prospect Park, the Grand Army Plaza Greenmarket, Brooklyn Museum, Brooklyn Botanic Garden, acclaimed restaurants, cafés & boutiques on 7 th Avenue, plus multiple subway lines.

Whether preserved as an elegant income-producing property, transformed into a spectacular single-family residence, or enjoyed as a sophisticated owner's home with substantial rental income, 894 Union Street is a rare offering that seamlessly blends historic provenance, meticulous stewardship, modern convenience, and enduring architectural beauty on one of Park Slope's most desirable landmarked blocks.
