About This Property

Welcome to The Summit House, an extraordinary modern architectural masterpiece boasting 3,963 square feet of exquisitely crafted living space in the main residence, perched at approximately 2,150 feet above sea level at the end of one of Rancho Cucamonga’s most private and elevated cul-de-sacs. This bespoke estate embodies a seamless fusion of precision engineering, sophisticated design, and elevated lifestyle. A striking 27-foot glass tower and floating portico announce your arrival, opening to a grand foyer defined by soaring ceilings and a sculptural glass staircase. The main living level is anchored by an 18-foot feature wall clad in slab marble with a fireplace, integrated bar, and expansive disappearing glass walls that dissolve the boundary between interior and resort-inspired grounds. Outside, 22-foot steel columns frame a covered patio overlooking a modern pool and elevated spa, meandering water features, a vineyard, orchard, and meticulously manicured lawns — all conceived for privacy, serenity, and visual harmony. The chef’s kitchen is a triumph of design, featuring Italian Stosa cabinetry, a dramatic 12-foot waterfall island, and fully integrated Thermador appliances. The residence offers three gourmet kitchens, opulent en-suite bedrooms, spa-caliber baths with advanced smart technology, and a primary suite with commanding mountain and valley views. An upper-level Sky Residence provides over 950 square feet of private quarters with its own entrance, kitchen, and bath — perfect for guests or extended family. Engineered for ultimate performance, the home is equipped with enterprise-grade networking, integrated security and surveillance, Lutron lighting, Sonos audio, multi-zone HVAC, dual tankless systems, and solar integration. With an approximately 30’ x 40’ finished showroom-style garage and meticulous attention to every detail, The Summit House is the pinnacle of modern architectural sophistication — where artful design meets unparalleled luxury living.
