557 Oceana Drive is a coastal retreat perched above the shoreline, where sweeping panoramic views unfold across Dillon Beach, Tomales Bay, Tomales Point, and out to the Pacific Ocean. Here, the rhythm of the coast becomes part of daily life, with shifting light, open sky, and expansive water creating a setting that feels both serene and deeply immersive. From the bedrooms to the main living areas, nearly every room captures a different vantage point of the coastline, creating a truly captivating coastal experience. Set on a generous 11,700 sq ft lot (over 1/4 acre), this 2,352 sq ft home is filled with natural light and designed to embrace its surroundings. The open floor plan features a soaring, dramatic redwood ceiling with skylights, a charming mid-century round glass fireplace, and multiple floor-to-ceiling picture windows that fully immerse the home in its natural setting. The home's distinctive octagon design enhances both form and function, allowing for unique sightlines and a dynamic relationship with the surrounding landscape. The kitchen is both sculptural and functional, featuring striking copper sinks and a generous island that serves as a natural gathering point for entertaining or unhurried mornings. The connection to the outdoors continues with a wind-protected balcony, offering a front row vantage point for sunsets and the ever-changing tones of the coastline. The overall space feels expansive yet warm, airy yet comfortable. The low-maintenance grounds enable easy coastal living, while a 2-car garage and additional driveway parking provide convenience for everyday living and guests. Over $500,000 in upgrades blend style with modern efficiency. The extensive improvements completed by the current owners include owned solar, Tesla Powerwall, EV charger, Hardie siding, Trex decking, dual pane windows and sliders, on-demand water heater, 2 HVAC systems with HEPA filtration, LVP flooring, roller shades, refreshed bathrooms, fresh interior and exterior paint, and much more.

The Oceana Marin community offers access to a scenic walking trail from Oceana Drive leading to the Estero de San Antonio sandbar, where coastal bluffs, open water, and a more secluded stretch of beach await. Located just moments from the beach, Coastal Kitchen, the General Store, and Surf Shop, this area is a surfer's paradise and a nature lover's dream, with one of Northern California's most beloved dog-friendly beaches.
