Occupying 40' of prime bay frontage along Newport Harbor's turning basin, 8 Beacon Bay enjoys sweeping south-facing views from within one of the area's most beloved waterfront communities. Spanning three levels connected by a private elevator, the residence is one of the largest in Beacon Bay - a distinction made possible by its expansive basement level, a feature that would be extraordinarily difficult, if not impossible, to recreate today. Custom built in 2010, the home offers over 5,000 square feet of living space with an intuitive floor plan designed for both everyday living and effortless entertaining. The upper level is anchored by an expansive primary suite with a sitting room, accompanied by two additional en suite bedrooms, a private office, and a dedicated laundry room. The main level is designed to maximize the waterfront setting, offering a light-filled great room that opens seamlessly to the dining area and chef's kitchen, appointed with premium Sub-Zero, Wolf, and Miele appliances, including a built-in coffee system, convection oven, microwave/speed oven, warming drawer, pot filler, and an oversized center island. A powder bath and a private en suite guest bedroom complete the main floor. The lower level serves as a true extension of the home's living space, featuring a spacious secondary family room, gym, temperature-controlled wine room, back kitchen, and a full bath with steam shower. Designed to embrace the waterfront setting, the home's outdoor living spaces include a rooftop deck with private spa and a bayfront terrace complete with a built-in barbecue, fire pit, and built-in seating for outdoor dining. Additional notable amenities include an oversized three-car garage, heated floors, zoned air conditioning, and a water filtration system. Founded in 1927, Beacon Bay remains one of Newport Beach's most distinctive residential enclaves, celebrated for its wide grass estradas and relaxed waterfront lifestyle. Residents enjoy exclusive access to private white sand beaches, boat docks and slips, tennis, basketball, playgrounds, and year-round community events that foster a true neighborhood atmosphere. Ideally situated just minutes from Fashion Island, Balboa Island, 17th Street and world-class beaches, 8 Beacon Bay offers an exceptional opportunity to enjoy one of Newport Beach's most unique and enduring waterfront communities. *Seller may consider buyer concessions if requested in an offer*
