About This Home

318 Avenida Costanso

Panoramic ocean and golf course views, a brand-new high-end remodel, and a rarely available Southeast San Clemente location come together at 318 Avenida Costanso. Perched above the San Clemente Municipal Golf Course, this 4-bedroom, 4-bath residence has been completely reimagined from top to bottom and has never been lived in since completion. Expansive views stretch across the golf course and Pacific Ocean from the Dana Point Headlands to Cottons Point. The home makes a striking first impression with incredible curb appeal and a coastal contemporary mid-century design that complements its surroundings. An all-new exterior, roof, windows, doors, and architectural details set the tone for what awaits inside. The main level begins with a formal entry providing access to the oversized two-car garage and an attached private casita. The casita features its own bedroom, living area, kitchenette, full bathroom, walk-in closet with laundry hookups, and private sauna. This unique space can function as guest quarters, a home office, gym, wellness retreat, or combination of uses. Upstairs, the home opens into a spacious great room with vaulted ceilings and panoramic Pacific Ocean and golf course views. The open-concept kitchen, dining, and living areas come together as the heart of the home, framed by large multi-slide doors connecting to the west-facing deck and California room—ideal for dining, entertaining, or relaxing while taking in the coastal setting. Adjacent to the kitchen, a covered backyard patio creates another outdoor living space overlooking the private rear yard. Three additional bedrooms are located upstairs, including the primary suite, each with its own en-suite bathroom. The primary suite features vaulted ceilings, a generous walk-in closet, and a spa-inspired bathroom finished with floor-to-ceiling stone. The private backyard features an in-ground spa, multiple areas for lounging and entertaining, and tiered planter beds with mature citrus trees. Nearly every element of the property has been upgraded, including a brand-new roof, air conditioning, windows, doors, exterior finishes, mechanical systems, and much more. Located just above the San Clemente Municipal Golf Course—known locally as “The Muni”—the home offers convenient access to the 5 Freeway and some of San Clemente’s best beaches and surf breaks, including world-famous Lowers Trestles. Project by Inspired Coastal Designs.
