With panoramic views stretching from Laguna Beach to Palos Verdes and one of the largest view lots in lower Crystal Cove, 12 Tasman Sea presents a beautifully updated coastal residence defined by refined interiors and abundant natural light. Encompassing approximately 5,210 square feet with five bedrooms and six baths, the home rests on an approximately 9,210-square-foot homesite with a new pool and spa and sophisticated improvements throughout. Beyond a charming entry courtyard with fireplace, interiors unfold in a warm palette of wood flooring, designer tile, porcelain surfaces, and statement lighting. A new chandelier, redesigned stair railing, hardwood stairs and upper hallway, and stone fireplace hearths lend a fresh architectural sensibility. The powder room features marble, designer wallpaper, and new fixtures, while a private main-level guest suite sits just off the entry. A mezzanine overlooking the foyer offers flexible space for an office, sitting area, or studio. Formal and casual living spaces capture sweeping ocean views. A brick-clad lower-level room offers space for a wine cellar or private office. The reimagined kitchen features new oak cabinetry, countertops, designer fixtures, a 48-inch refrigerator, updated pantry shelving, breakfast nook, and center island with bar seating. Open to the family room and outdoors, it creates an effortless setting for living and entertaining. Nearby, the redesigned laundry room includes custom cabinetry, porcelain countertops, sink, and an additional Sub-Zero refrigerator. Upstairs, the remodeled primary suite offers ocean views, a sitting room, custom closets, and an updated bath with new cabinetry, countertops, flooring and fixtures, soaking tub, and porcelain-clad shower. Three additional ensuite bedrooms complete the upper level, including two that may be combined as a private guest suite with separate exterior stair access. Outside, new landscaping and hardscape frame the pool and spa, complemented by a built-in BBQ island, retractable awning, and heaters. New exterior doors from the living room enhance indoor-outdoor flow, while a new concrete driveway, stone-clad entry steps, and refreshed front courtyard elevate the arrival. Within Crystal Cove’s 24-hour guard-gated setting, residents enjoy several parks including The Canyon Club with pool, spa, fitness/banquet spaces, sport courts, and private neighborhood access to Crystal Cove State Park, beaches, and the shopping and dining of the Promenade.
