Embodying classic mid-century California architecture, this timeless single-level home is set behind the exclusive 24-hour guard-gated enclave of Monarch Bay. Positioned on one of the neighborhood's larger private lots, it offers exceptional potential in a highly sought-after coastal community. Recently updated including a new presidential roof, the residence is turnkey and livable as-is, with long-term potential to reimagine or expand. Inside, the airy open floor plan centers around a sunlit family room with vaulted cathedral ceilings and a statement fireplace adding warmth and architectural character. The formal dining area is perfect for entertaining beneath an elegant chandelier, while the kitchen features chic quartz countertops and ample storage. Large openings with sliding doors create a natural flow between indoor and outdoor living, extending the space into the California sunshine. The primary suite serves as a private retreat with a sitting area and direct access to the outdoors, offering a true indoor-outdoor experience. Three of the four bedrooms feature en-suite bathrooms, and all open to outdoor spaces. The nearly 12,000-square-foot flat lot backs to Monarch Bay's private park with direct gated access, providing a perfect canvas for a resort-style backyard with pool, spa, and custom amenities. Residents enjoy exclusive membership to the private Monarch Bay Beach Club, managed by the Waldorf Astoria, offering beach butler service, coastal dining, oceanfront lounging, and private event space. Convenient access to world-class golf, hiking, Dana Point Harbor, and luxury resorts completes the unparalleled lifestyle.
