About This Home

Live expansively in this rare, 3,500+ square foot duplex - loft - condo, blending industrial charm with sleek modern design.

Set beneath soaring 12-foot ceilings, this expansive loft is currently configured as an upper level one-bedroom (easily convertible to a two-bedroom) and a lower level featuring a spacious dance studio with a dedicated office and a den / guest room.

Whether you envision a chic home for living and entertaining, or a bold launchpad for your creative or entrepreneurial pursuits, this space offers unique versatility: fully residential, fully commercial (wellness, studio, boutique retail, caf ), or a blend of both.

The upper level of the loft is luxurious, showcasing craftsmanship and comfort through its red oak hardwood floors, exposed brick walls, intricate tin ceilings, wood-burning fireplace, and artisan ironwork throughout.
The chef's kitchen is both functional and beautiful, with rich cherry wood cabinetry, handcrafted tile-work, a convection oven and dishwasher. The spa-inspired bathroom is a calming retreat with terra cotta tiles, an open rainfall shower, and a classic clawfoot soaking tub. Additional highlights include a dedicated laundry room, a generous walk-in closet, and abundant built-in storage.

Follow the interior staircase down to a truly transformative space: the dance studio with mirrored walls, resilient sprung wood floors, gorgeous exposed brick, a half bathroom and two additional rooms.

This gas-free residence is built with sustainability in mind, featuring split-system HVAC on both levels and an energy-efficient, on-demand hot water system.

Centered amongst picturesque brownstone streets and moments from vibrant boutiques and eateries of 5th Avenue in Park Slope. Just minutes from Brooklyn Museum and Prospect Park the neighborhood offers an unparalleled blend of history, creativity, and multiple train lines.

Now, it's waiting for the next visionary to make it their own!
