Property Description for 725 Union Street, 1

An extraordinary Park Slope residence that defies expectation.

With over 3,500 square feet, this loft condominium combines industrial charm, a beautifully crafted environment, and remarkably low monthly costs. Set beneath 12-foot ceilings, this duplex is configured with an upper level one-bedroom (easily convertible to two) and a lower level featuring a spacious dance studio, dedicated office, and guest room.

Upon entering the loft, the grand scale and architectural artistry of the great room immediately impress. Exquisite red oak hardwood floors, exposed brick walls, tin ceilings, a wood-burning fireplace, and bespoke ironwork create a space that is both dramatic and inviting. The large chef's kitchen has rich cherry wood cabinetry, handcrafted tile-work, a convection oven and dishwasher. The bathroom is stunning. It's a spa-inspired space with marble & stone tiling, an open rainfall shower and a clawfoot soaking tub. A staircase, framed by built-in bookshelves, leads to the sleeping loft, a lovely room perched above the great room and bathed in soft light. There is also a dedicated laundry room, a large walk-in closet, and 3 additional storage closets.

The lower level opens to a professional dance studio, but if dance isn't your passion, this flexible space can be reimagined as an entrepreneurial space, architect's office, wellness studio, recreation room, or guest retreat. This gas-free home is designed with sustainability in mind, featuring split-system HVAC on both levels and an energy-efficient on-demand hot water system.

This exceptional property offers rare versatility - fully residential, or a sophisticated fusion of home, business, and pleasure. Opportunities of this scale and adaptability rarely appear in the Park Slope market. Claim your place here and shape its next chapter, surrounded by Brooklyn's fantastic cultural hubs, the beauty of Prospect Park, and the vibrant shops and eateries along 5th Avenue.

Park Slope | Brooklyn

Quick Profile

Boasting beautiful tree-lined streets, brownstones and a range of activities for all age groups, Park Slope is consistently ranked as one of New York’s most desirable neighborhoods. Filled with lush parks and greenery, the neighborhood is also known for its rare combination of excellent public schools, award-winning restaurants, nightlife, small independently owned businesses and community gardens.

Situated at the western slope of Prospect Park, the neighborhood is divided into different sections: North Slope, Center Slope and South Slope. Depending on who you ask, of course, the definitions of where these borders end and begin may vary (is the divide between North and Center deemed Union Street, Garfield Place, 1st Street or 3rd Street? The one between Center and South 6th Street, 9th Street, 11th Street or 15th Street?). 

Regardless of what part of the Slope you find yourself on, there’s no shortage of architectural beauty. From row houses to brownstones to mansions, the idyllic setting of the neighborhood is further enhanced by its Romanesque and Renaissance Revival styles. Case in point of this is also two of the area’s most well-known churches, Park Slope United Methodist Church and Saint Augustine Roman Catholic Church. 

Revered for its family-friendly appeal, Park Slope is often regarded as one of the best places to raise a family in New York City. That said, it doesn’t mean that parents don’t know how to have a good time... a slew of bars constantly opening in the neighborhood ranging from the high-end cocktail saloon to the dive (well, by Park Slope standards, anyway).
