About 6389 Castejon

An extraordinary expression of modern coastal luxury, this La Jolla estate pairs architectural sophistication with resort-caliber amenities. Set on a half-acre hillside parcel, the newer-construction residence offers more than 8,000 square feet of living space. A reverse floor plan creates an exceptional scale and flow, with select interior vantage points offering views toward the Pacific and the expansive backyard serving as the centerpiece of its coastal setting. Six bedrooms, seven full baths, and two half baths include two exceptional primary suites, while kitchens on multiple levels, a fitness room, elevator, and dumbwaiter provide effortless functionality. The main level is designed for elevated entertaining, with an indoor bar, 180-bottle wine room, and lounge opening to a private courtyard anchored by a dramatic 20-foot cascading water feature. The primary suite offers a private patio and outdoor shower. The expansive backyard is where this estate truly comes alive, with an infinity-edge pool, outdoor kitchen and bar, and coastal vistas creating an ideal setting for entertaining. Ocean-view basketball and bocce courts further elevate the resort-like experience. Refined finishes include Wolf and Sub-Zero appliances, Waterstone fixtures, built-in espresso machines, warming drawers, onyx countertops, stone accent walls, and wide-plank LVP flooring. Ideally positioned near La Jolla's beaches, private golf courses, trails, schools, and renowned dining, this estate offers a rare opportunity for sophisticated coastal living.
