Renovated Loft Building in Prime Park Slope
A truly rare offering, 676 Union Street is a 25-foot-wide loft building in the heart of prime Park Slope, encompassing approximately 6,500 square feet of beautifully renovated space. Combining the scale and openness of a downtown loft with the warmth and character of classic Brownstone Brooklyn, this exceptional property presents a unique opportunity in one of the borough's most coveted neighborhoods.
Currently configured as two expansive duplex residences and a dedicated gallery/studio, the building offers six bedrooms and five-and-a-half bathrooms, providing remarkable flexibility for end users, investors, or those seeking an exceptional live/work environment.
Each duplex is distinguished by soaring ceilings, oversized windows, wood-burning fireplaces, and abundant natural light. The building has been thoughtfully restored from the brick out, blending its authentic loft character with modern infrastructure, high-quality finishes, and long-term durability. Custom wood staircases connect each level, creating a seamless sense of flow while emphasizing the home's impressive scale and volume.
The upper floors enjoy expansive skyline views, enhanced by generous ceiling heights and skylights that bathe the interiors in natural light throughout the day. Above, a private rooftop terrace offers a spectacular outdoor retreat with sweeping city vistas, ideal for entertaining or quiet relaxation. At the garden level, a serene south-facing courtyard inspired by Mediterranean design features stone-tiled flooring and lush outdoor living space rarely found in this part of Brooklyn.
The ground-floor gallery and studio, complete with a private entrance, kitchenette, and powder room, provides exceptional versatility as a creative workspace, home office, showroom, or studio. Its independent access allows it to function separately from the residential spaces while remaining fully integrated into the property.
Perfectly situated on Union Street, the building is moments from Park Slope's acclaimed restaurants, boutiques, cafés, parks, and transportation, offering convenient access throughout Brooklyn and Manhattan. Its exceptional width, generous scale, and adaptable layout present a rare opportunity to create an extraordinary single-family residence, maintain two expansive duplex homes, or explore a condominium conversion, subject to all required approvals.
Offering an exceptional combination of size, light, architectural character, skyline views, and flexible living, 676 Union Street is a one-of-a-kind property in one of Brooklyn's most established and sought-after neighborhoods.
All prospective purchasers are encouraged to independently verify square footage, dimensions, permitted uses, and all other information to ensure the property meets their individual requirements and complies with applicable regulations.
