Experience the quintessential waterfront lifestyle you have dreamed of at this luxurious Newport Beach home on Harbor Island Drive. Nestled at the edge of Promontory Bay, the spacious five-bedroom, four-bath residence presents water views from both levels and its large backyard patio, which spans 50 of bay frontage and leads to a private dock with three slips, featuring a premium Brazilian hardwood surface. Handsome brickwork complements the front yard, where custom double doors introduce a light and airy setting with upscale nautical aesthetic. A two-story foyer makes a dramatic first impression and offers passage to an office/fifth bedroom on the main floor with extensive built-ins, bamboo flooring, and a tray ceiling. Yacht vibes are enjoyed in the bonus room, complete with access to a private brick courtyard, vaulted and beamed ceiling, porthole windows, lacquered wood floors, slate-surround fireplace, and a walk-in bar with Scotsman ice maker and refrigerator. Polished stone floors lead the way beyond the courtyard to a formal dining room with private side patio, and a wide-open living room and family room space with bay views and multiple French doors leading to the bayfront patio. A sleek stainless-steel-trimmed fireplace warms the living room, and the family room features a built-in entertainment center with surround sound. Classic white cabinetry and granite countertops with full backsplash lend an air of upscale refinement to the kitchen, where an oversized island with prep sink, access to the dining room, and stainless steel appliances are proudly displayed. High-end patterned carpet distinguishes second-floor areas including one private en suite bedroom and two bedrooms that share a bath. Overlooking the bay, the primary suite is appropriately grand. Enjoy a handsome fireplace, grasscloth wallpaper, sitting area, view balcony, walk-in closet with custom built-ins, two sinks, a jetted tub and separate shower. Millwork including crown molding is showcased, and a two-car garage includes built-in storage.
