Carved into the hills overlooking the tree-filled Hudson Valley and Palisades, this 3 level masterpiece boasts elegance and luxury throughout. An open and airy retreat, reminiscent of a celebrity's hideaway in the Hollywood Hills, this sun-flooded jewel offers a wow factor at every turn.   The main entrance opens onto an entry foyer, leading to a sprawling loft-like space with a wall of windows (19!) spanning the entire floor. The large dining area flows into a sleek and modern kitchen with two oversized waterfall islands and an open family room with a modern gas fireplace and doors leading out to a large balcony. The sunsets are divine.   Down one level are three bedrooms, two connecting, with doors that open out to the full-floor balcony, a full hall bathroom, and the laundry. At the end of the hall is the primary suite - with two massive walk-in closets, a spa-like en-suite bathroom, and entry to the balcony.   The lower level has another full hall bathroom and an additional 1104 SF of finished, heated spaces - currently configured as 2 home offices, a guest room, and a home gym. On this level, you can also access the multi-leveled patios, rear yard with a swing set, and a screened-in porch.   Located on a cul-de-sac at the very top of a quiet dead end street, this one-of-a-kind home has been featured in multiple international publications. Close to Whole Foods and all the shops, restaurants, and attractions in the villages of Hastings-on-Hudson and Ardsley. Convenient to several major roadways, for a fast trip into the City, and just 39 minutes on Metro North to Grand Central.
