Perched at the top of the prestigious Hidden Hills neighborhood of Yorba Linda, 4855 Green Crest Drive is a ONE-OF-A-KIND ARCHITECTURAL GEM offering PRIVACY, PANORAMIC VIEWS, AND LUXURY AT EVERY TURN. With no neighbor in front, the home captures sweeping canyon and sunset views, while the backyard opens to unobstructed city lights, creating a serene setting to unwind after a long day. From the moment you step through the custom glass entryway, you're greeted by dramatic ceilings, a contemporary chandelier, and an opal white satin marble staircase that sets the tone for the rest of the home. Natural light floods the space, while French oak hardwood floors add warmth and sophistication highlighting the seamless flow and elegant finishes throughout. The formal living room centers around a striking floor-to-ceiling quartzite fireplace, while the adjacent dining room is surrounded by picture windows that frame peaceful garden views. The heart of the home is the chef's kitchen, featuring dual-tone European-style custom cabinetry, quartz counters, and a frameless bay window that invites the outdoors in. Outfitted with SubZero and Wolf appliances, and a generous center island with waterfall counters, this kitchen is as functional as it is beautiful. Just off the kitchen, a casual dining nook and spacious family room make everyday living feel elevated. The main level also offers an ensuite bedroom, ideal for guests or multigenerational living, along with a versatile flex space perfect for a home gym or office. Upstairs, the primary suite is a true retreat with its vaulted ceilings, cozy fireplace, spa-like bath with large marble shower, dual sink, freestanding bathtub, and two large custom walk-in closets. Step onto the private balcony to soak in the breathtaking views, day or night. A large upstairs bonus room with canyon views and full bath offer endless possibilities, whether as an additional bedroom, media room, or playroom. Each bathroom has been thoughtfully designed with iron and marble Hudson vanities with frameless glass tiled showers. The expansive backyard is designed for unforgettable gatherings, with multiple entertaining and dining areas, a large pool and spa, BBQ island, and postcard-worthy views in every direction. Additional features include a PAID 52-panel solar system, EV charging, motorized shades, designer lighting, modern HVAC vents, and 3-car garage. This is not just a home, it's a statement of timeless design, comfort, and California luxury.
