Property Description
ALESSANDRO HEIGHTS | STELLAN RIDGE- ***ASSUMABLE FIRST LOAN OF $865,000 AT 2.25% FIXED RATE UPON APPROVAL*** Perched atop prestigious Stellan Ridge in Alessandro Heights, this secluded hilltop estate offers a masterclass in design, scale, and panoramic views. Surrounded by open space and framed by sweeping city lights and mountain vistas, the property is a true sanctuary crafted for both refined entertaining and effortless daily living. Beyond the private gates, a circular paver motor court and lush Mediterranean landscaping set a sophisticated tone. The journey begins in the front courtyard, leading into an expansive foyer where formal living spaces immediately draw the eye through to the rear of the home, framing the pool and the horizon beyond. The heart of the residence is a massive island kitchen that flows seamlessly into the Great Room, with a butler’s pantry providing a graceful transition to the formal dining room. The layout is thoughtfully divided to prioritize privacy. One wing houses a quiet study and a secluded primary suite, featuring a completely remodeled bath and an impressive walk-in closet. In the opposite wing, you’ll find a state-of-the-art home theater—thoughtfully created by combining two bedrooms (easily reversed)—alongside additional guest quarters and two beautifully updated baths. The outdoor living spaces rival the world’s finest resorts. An enclosed loggia opens to a spectacular pool and spa area, complete with a cabana, fire pit, and a separate jacuzzi. A slide leads to a lower plunge and lap pool, creating a tiered oasis of relaxation. The grounds are fully fenced and cross-fenced, offering ample off-street parking and a dedicated RV/boat pad. An additional amenity the natural gas powered generator insuring there is no loss of power to the property in the event of a power outage for any reason. Presented in pristine, turn-key condition, this is a rare opportunity to own a one-of-a-kind retreat that feels worlds away while remaining close to everything.
