18431 Coastline is a truly exceptional ocean-view lot in Malibu's beloved Sunset Mesa enclave, offered with fully permitted plans and shovel-ready approval to build a stunning 3,166-square-foot residence featuring 4 bedrooms and 4.5 baths. This will save months of your time! Located on one of the premier view parcels in Sunset Mesa locally known as "the Mesa", this rare pie-shaped 7,723 sq ft lot allows for sweeping ocean views from the majority of the home's rooms, a feature seldom found in the neighborhood. The thoughtfully designed floorplan maximizes both the lot and the views, offering an open, flexible layout. Plans include space for a formal backyard, expansive deck, and spa, with the option to add a pool if desired. The project has already been approved by Sunset Mesa's Architectural Committee, making this an exceptionally rare, ready-to-build opportunity. Sunset Mesa is one of Malibu's few master-planned ocean view communities, featuring underground utilities, wide sidewalks, extra-wide streets, no parking restrictions, and protected views enforced by CC&R regulations. The home also boasts a generous backyard and an oversized front balcony perfect for entertaining, with panoramic views stretching from the sandy beaches to the Santa Monica Pier. By night, the coastline lights along PCH create a magical glow across the ocean. Residents enjoy access to the highly regarded Malibu School District, known for its approximately 15:1 student-teacher ratio and neighborhood bus pickup. The Mesa offers exceptional privacy with no retail and no through streets, yet remains conveniently close to Santa Monica (3 miles), the Palisades (1.5 miles), and downtown Malibu (4 miles). Best of all, the beach is just minutes away!
