Available for the first time in nearly two decades, 25 San Mateo Way is one of the most iconic offerings in Corona del Mars Spyglass Hill. Set on an extraordinary oversized lot with rare positioning, this trophy estate captures sweeping, unobstructed views that span Newport Coasts hillsides, Pelican Hill Golf Course, the Pacific Ocean, Catalina Island, Newport Harbor, Fashion Island, and sparkling city lights stretching to downtown LA. A private gated driveway leads to the residence, where approximately 7,109 sqft of interior living space is complemented by nearly 720 sqft of covered outdoor loggia space. Nearly every room in the home embraces the panoramic vistas and unparalleled privacy. The main level begins with a grand foyer and features a formal living room, wine room & tasting area, sunroom retreat, and an expansive great room that blends the family room, kitchen, and informal dining for 10+. Frameless glass bi fold doors extend the interiors to the backyard sanctuary. A main level ensuite bedroom offers comfort for guests. The upper level hosts 4 additional bedrooms, including an executive office with retreat and a large loft/media room. In total, the home offers 5 bedrooms plus office, bonus room, optional gym or private den, multiple living areas, and exceptional flexibility. Resort like grounds create a setting designed for both entertainment and everyday enjoyment. Highlights include a pool with slide, spa, waterfalls, built in BBQ island, crushed seashell bocce ball court, water features, and two covered loggia spaces: one designed for dining al fresco, the other for lounging with a fireplace and television. The meticulously maintained landscaping evokes the romance of Tuscany and offers multiple seating points to enjoy the endless views. With its gated entry, oversized driveway, 3 car garage, and unique setback that ensures unusual privacy, 25 San Mateo Way stands apart as a truly one of a kind opportunity. Combining iconic views, timeless design, and a legacy lot, this estate represents the very best of coastal Orange County living just a stones throw from premier shopping and dining at Fashion Island and the CdM Village, five star luxury resorts, award winning schools, John Wayne Airport, and convenient freeway access.
