When architect David Hotson paired up with interior designer Ghislaine Vinas to design Manhattan's infamous SkyHouse penthouse, we knew something good was to be in store. The stunning four-story space, located at the top of a Central Park skyscraper, features panoramic views of the city, an interior rock wall, and hidden nooks with picture-perfect vistas of classic NYC landmarks. The best part? An indoor 80-foot slide that extends from the attic to the dining room. You won't want to miss this.
