From its gated hillside location on nearly six acres, this distinguished estate showcases dramatic, sweeping views of the Pacific Ocean and Channel Islands, offering an alluring convergence of serenity, seclusion, and exceptional craftsmanship. Originally designed by architect Don Nulty and substantially renovated by its current owners, the 9,700+ square-foot residence is beautifully appointed for both quiet respite and effortless entertaining. Throughout the property, desirable amenities abound, including a stunning infinity-edge pool, meticulously tended grounds, and a private shared well that sustains the estate's lush landscaping. An olive-lined drive winds along the hillside, gracefully introducing the motor court and stately front entrance. The home’s thoughtful floor plan operates comfortably on a single level, flowing naturally between grand entertaining spaces and intimate retreats, while offering generous accommodations for family and guests on the upper and lower levels. Inside the front doors, arched openings frame the foyer and draw the eye immediately toward the ocean beyond. The living room is both impressive and inviting, anchored by an oversized marble fireplace. An adjacent formal dining room features sculptural pendant lighting and direct access to the south-facing terrace. The spacious kitchen offers striking design, custom cabinetry and abundant countertop space, high-end built-in appliances, and herringbone oak floors, with an adjoining breakfast area opening to an ocean-view patio. A cozy media room and a moody library with floor-to-ceiling built-ins and a fireplace offer more intimate spaces, while an office, a spacious laundry room, and an attached three-car garage complete the main level. Situated in its own wing of the home, the primary suite features dual en suite bathrooms of exceptional finish, dual custom walk-in closets, and views of the ocean and mountains. Two additional en suite bedrooms occupy the lower level, while an upper guest wing offers its own sitting room, ocean-view terrace, and en suite bath — ideal for family or guests seeking their own retreat. Outside, a south-facing terrace and loggia surround a spectacular ocean-view infinity-edge pool. Multiple seating areas and an outdoor fireplace invite year-round enjoyment of the dramatic views extending to the Channel Islands and beyond. Below the pool and terraces, the expansive grounds unfold across the hillside in carefully tended gardens of roses, lavender, native plantings, fruit trees, terraced seating areas, and winding gravel paths — all sustained by a shared private well. Located within a gated enclave of just three estates and yet just moments from Montecito's Upper Village, 1140 East Mountain Drive is a rare and irreplaceable offering above one of California's most beloved coastal communities.
