Inside Sky House: The NYC Penthouse Where the Fastest Way Downstairs Is a Slide

Tucked into a 130-year-old building at 150 Nassau Street, "Sky House" is proof that grown-up luxury and pure childlike fun don't have to live on separate floors. Designed by interior designer Ghislaine Viñas, this one-of-a-kind, four-level penthouse is a dreamscape where art, design, and architecture collide. As Viñas explains in Open House TV's latest tour, the project came together over a decade ago, and the result is a space that feels equal parts gallery and playground — anchored by soaring 46-foot ceilings and two terraces with sweeping views of the Manhattan skyline.

The home spans four bedrooms and five bathrooms, plus a chef's kitchen engineered with clever hidden storage, but it's the sense of play that steals the show. A giant spiral slide offers the quickest route downstairs, while a rock climbing wall, a rope swing, and a catwalk turn the architecture itself into something to interact with. Even the more traditional rooms carry that spirit of whimsy: the grand living room pairs classic smoking chairs with a sleek, modern tufted sofa, all bathed in the kind of natural light that pours into a turn-of-the-century building with this much vertical drama.

What makes Sky House so compelling isn't just the spectacle — it's the reminder that a home can be sophisticated and joyful at once. It's a rare listing that invites you to climb, swing, and slide through it, and a fitting reminder that, in Viñas's vision, adults deserve to have a little fun too.
