Set within Malibu's coveted Sunset Mesa enclave just 2 blocks from the white sandy beaches along iconic PCH, 18431 Coastline presents rare opportunity to build on one of "the Mesa's" premier ocean-view parcels. Offered with fully-permitted plans and shovel-ready approvals, this remarkable offering eliminates months of entitlement and design work, allowing you to move directly toward construction of a thoughtfully designed 3,166-square-foot contemporary residence with 4 bedrooms and 4.5 baths. Positioned on 7,723-square-foot lot, the property captures sweeping ocean vistas from nearly every major living space an uncommon advantage even within Sunset Mesa. The architectural plans have been carefully designed to maximize both the site and its extraordinary view corridors, featuring an open-concept floorplan where the living, dining, and kitchen spaces seamlessly connect to expansive walls of glass framing the Pacific Ocean from the front, and the surrounding Malibu hills from the back. Outdoor living is equally compelling, with plans for a generous backyard, expansive view deck, and spa, plus the flexibility to incorporate a pool if desired. Already approved by Sunset Mesa's Architectural Committee, this is a truly turnkey development opportunity in one of Malibu's most established and tightly held coastal communities. Sunset Mesa is one of Malibu's few ocean-view neighborhoods, distinguished by underground utilities, broad sidewalks, and extra-wide streets. Designed for both privacy and convenience, the community offers a rare sense of seclusion with no through streets or commercial traffic, yet remains just minutes from Santa Monica, Pacific Palisades, downtown Malibu, and some of Southern California's most iconic beaches. This truly is an extraordinary offering in one of Malibu's most sought-after coastal neighborhoods.
