This contemporary showpiece on Newport Beach's prestigious Harbor Island Drive exemplifies bayside luxury. Designed by the renowned architectural firm of CJ Light Associates, it features Maynard Interior Design-curated interiors with globally sourced finishes. Expansive bay views can be enjoyed from the indoor and outdoor living spaces, combining modern elegance with the essence of waterfront living, including a private dock suitable for berthing a 55' vessel. Panoramic vistas take center stage on the main level, which consists of a dramatic double-height entryway with a floating cantilever staircase, a temperature-controlled walk-in wine cellar, and an expansive great room with a dining section, a home bar, and access to the exterior and the docks via automated pocket doors. The gourmet kitchen, adorned with select appliances by Scotsman, Miele, Gaggenau, and Sub-Zero, features a center island with seating, stone countertops, bespoke cabinetry, and convenient access to the front and rear exterior areas. This property encompasses four ensuite bedrooms with walk-in closets, a ground-floor office with access to the outside, an upper-level multipurpose space that could function as a home theater or a lounge, and a flex room ideal for a gym. The water-facing primary suite is genuinely opulent, with a five-piece bath, a balcony, a massive walk-in closet, and a linear fireplace. Harbor Island Drive offers two distinct outdoor areas: a front patio with a fire pit, a dining section, and an inground spa, as well as the oversized bayfront space with a cantilever sea wall in the rear of the residence. Additional highlights of this exceptional offering include a three-car garage, an elevator, laundry rooms on each level, custom closet systems, inset lighting, rift-cut white oak flooring, and whole-house automation by Lutron and Savant.
