Brooklyn developer Craig Rosenman, director of acquisitions at the Daten Group, is listing his Brooklyn condo for $8.25 million at 2 Northside Piers.

The sprawling, 4,522-square-foot duplex features five bedrooms, five bathrooms and two powder rooms. It’s on the 20th and 21st floors of the 31-story building and overlooks the Williamsburg waterfront — boasting stunning views of the Manhattan skyline.

The residence is a combo of three separate two-bedroom condos, overseen by Swedish designers at Cortina & Käll.

The home opens to a foyer that leads to a glass-and-steel spiral staircase, which anchors and connects the home.

There’s a chef’s kitchen, with marble and custom cabinetry, including a 150-bottle wine fridge and a study/home office space with built-ins and its own terrace. 

There’s also 1,104 square feet of outdoor space over three balconies and — for a separate, additional undisclosed purchase — an 822-square-foot private rooftop cabana tricked out with water, electricity, gas, an outdoor kitchen, irrigated landscaping, lighting and a heat lamp.

Past residents include actress Christina Ricci and A-Trak, the Canadian DJ turned music exec — Alain Macklovitch. The building, which dates to 2010, includes amenities like a pool and hot tub, gym, massage and yoga rooms, screening rooms, a children’s playroom and cold storage.

There’s also a 400-foot pier outside the building and water esplanade with access to the East River Ferry. Oh, and real estate taxes are minimal thanks to 15 years left on a 421a tax abatement. The listing broker is Ralph Modica, of Compass.
