Situated in the prestigious enclave of Irvine Terrace, Corona del Mar, 1521 Bayadere Terrace presents a rare opportunity to own a custom-built coastal estate on an expansive 16,000+ square-foot lot. Primarily a single-level home, enhanced by a versatile lower level ideal for entertaining or family gatherings. The modern architecture, open-concept, and effortless indoor-outdoor integration define the property, while its scale, style, and picturesque views elevate everyday living. Designer furnishings may be available, offering a seamless move-in opportunity. The design connects each space with light and expansive views of Newport Harbor, the Pacific Ocean, and magical sunsets. Pocketing glass walls dissolve boundaries, immersing the interiors in sunlight and coastal scenery. French white oak flooring adds warmth and refinement, softening the clean architectural lines and creating a cohesive, elevated flow between rooms. Two distinct living areas anchor the main level: a formal living room with a dramatic fireplace, and a spacious great room. Both spaces open to the pool terrace, offering seamless indoor-outdoor living. The kitchen is a focal point of both design and performance, centered around a showstopping La Cornue range, complemented by porcelain countertops, iron open shelving, and a fully equipped secondary catering kitchen with Wolf and Sub-Zero appliances. The expansive primary suite features floor-to-ceiling glass, sweeping views, a spa-inspired bath with a freestanding concrete soaking tub, oversized shower, and a custom walk-in closet. The main level also includes three additional en-suite bedrooms and a refined home office. Outside, the resort-like experience continues: a dramatic infinity-edge pool and spa, heated covered terrace, and lush landscaping create a private oasis for year-round enjoyment. The lower level transitions into full entertainment mode. A stunning lounge with multiple seating areas, billiards space, and a striking bar provides the ultimate setting for hosting. Also included is a four-car garage with abundant storage and a mechanical room. Smart home automation is fully integrated, with a Crestron system controlling pocketing glass sliders, climate, lighting, audio, and security, paired with solar power for enhanced efficiency and sustainability. All just moments from the beach, harbor, Balboa Island, and the best of Corona del Mar, a highly livable coastal lifestyle built to enjoy.
