Offered by the original owners, this truly one-of-a-kind penthouse atop Williamsburg’s Mill Building has been dubbed the “House on the Roof,” but it could easily be mistaken as a luxurious mountaintop chalet. The red-roofed two-bedroom penthouse is wrapped in glass that opens to a massive rooftop terrace complete with a full kitchen setup. And it’s now asking $2.85 million.

You’ve gotta see this one

Perfume and fashion heiress Pauline Rochas and partner Carole Beaupré, the impossibly chic and creative photographer couple who currently own this 2,082-square-foot, one-bedroom-plus-office in Williamsburg’s Mill Building at 85 North Third Street, have listed the fashionably renovated loft for $2.585 million.

Ms. Rochas is the granddaughter of the late Hélène Rochas, stylish socialite, perfumer and wife of couturier Marcel Rochas; she and Ms. Beaupré run a photography studio, Coolife, that specializes in shooting still-life beauty images for brands like Chanel and Ralph Lauren, and collaborated on a line of perfumes (h/t LLNYC). The pair purchased the home for $940,000 in 2007 and have since elevated it to a level of polished north Brooklyn cool befitting their lifestyle as well as their neighborhood.

Tour this chic Williamsburg loft

You might not associate Carroll Gardens with industrial loft buildings, but rather with quaint brick row houses and the charming landscaped front gardens that give the neighborhood its name. But the Mill Building at 376 President Street is a fine example of the former (There’s a building by the same name in Williamsburg that was once home to supermodel Agyness Deyn, if you’re confused). Similar to Park Slope’s Ansonia Court, which so many love for its rustic, almost-gritty Brooklyn factory charm, this 55-unit former jute factory offers a rare warmth and period details unique to this kind of converted industrial building. It’s no less a modern condo though, with an elevator, parking and central A/C. This compact one-bedroom loft, asking $770,000–it last sold for $440,000 in 2012–has been updated with custom interiors that make the best of the apartment’s factory bones.

Have a look

There’s an exquisite loft in Williamsburg’s historic Mill Building available for $2.65 million. The one-bedroom stunner stands out from the rest with sumptuous upgrades contrasted with original detail like restored wide-plank floors and prewar beams. True, some of the fun, quirky elements—like the Warhol-esque paintings on the red wall and the trendy furniture—don’t come with the condo, but it’s still the perfect blend of character and luxury.
