This newly constructed residence delivers a modern living experience defined by sweeping ocean views across Laguna Beach, high-quality materials, strong architectural lines, and a seamless indoor-outdoor flow. Thoughtfully positioned to capture western light and coastline panoramas, the layout is efficiently designed with no wasted space and is served by an elevator connecting all floors. The main living areas are positioned to allow for effortless flow to expansive outdoor terraces through large Western pocket doors, each framed by raised green planters that add texture and a natural counterpoint to the home’s clean architectural lines. Living, kitchen, dining, and bar spaces are open yet clearly defined, finished with limestone flooring, custom Italian cabinetry, and integrated lighting throughout. The kitchen is equipped with a full Thermador appliance package including dual dishwashers, integrated refrigerator and freezer, wine storage, built-in coffee system, steam microwave, and a full pantry. Italian marble countertops are used throughout the kitchen, bar, powder room, and fireplaces, while secondary bathrooms feature Spanish porcelain and full-height imported wall finishes. The upper level includes a primary suite and two additional ensuite bedrooms. The primary suite features motorized shades, a linear gas fireplace, custom walk-in closet, and a bathroom finished in Italian marble slab. A guest suite with walk-in closet and full bath is located near the main entry level, offering privacy and flexibility. Construction is predominantly steel and reinforced concrete, including twelve-inch exterior concrete walls, a concrete podium spanning the first level, and a foundation supported by more than forty-eight deep caissons. The garage offers 16-foot ceilings with capacity for vehicle lifts. Approved ADA-compliant plans for an additional dwelling unit are included, allowing for approximately 848 square feet of additional living space.
