Located within Corona del Mar's Spyglass Hill enclave, 53 Montecito is a newly constructed estate capturing approximately 270 views of Newport Harbor, the Pacific coastline, Back Bay, city lights, and mountain ranges. Commanding an elevated corner parcel with no direct neighboring structures on three sides, the residence enjoys expanded view corridors where horizon, harbor, and sky converge. Spanning approximately 7,584 square feet on a 15,740-square-foot lot, the six-bedroom, eight-bathroom home was conceived and executed as a primary residence with architectural expression and engineering precision prioritized. Arrival unfolds through a 60-foot gallery with 22-foot ceilings, aligned through walls of glass to the infinity-edge pool and Pacific horizon beyond. Floating steel-and-glass stairs, a living moss installation, and water features anchor the space. Architectural concrete panels, white oak detailing, and uninterrupted ceiling planes form a refined presentation. The great room opens to the outdoors through a 35-foot pocketing glass wall and zero-post corner systems. Entertaining spaces flow to reflecting pools, fire elements, and outdoor living areas framed in cedar and concrete, oriented toward sunset views. At the center of the home, the kitchen is anchored by a backlit Cristallo quartzite waterfall island. Pitt cooking systems, Wolf and Sub-Zero appliances, cabinetry, a Cristallo quartzite wine wall, and a secondary prep kitchen combine presence with performance. Whole-home water filtration and reverse osmosis systems serve key fixtures and refrigeration. Two primary suites offer flexibility. The upper-level primary suite opens to a terrace capturing harbor and ocean views. Taj Mahal stone, slab shower construction, a walk-in closet, oak paneling, and integrated lighting define the space. A lower-level primary suite provides accommodations for guests or multigenerational living. Amenities include a 10-seat theater with ballistic-grade reinforcement, fitness and wellness spaces, elevator access to all levels, infinity-edge pool with spa, and water features. Technology includes Josh.AI automation, Lutron lighting control, security and camera systems, structured wiring, and six zoned HVAC systems. 53 Montecito represents an opportunity to acquire a contemporary estate-an elevated coastal residence crafted for those who value design, privacy, and panoramic views.
