Experience a masterclass in modern design at 1689 Sunnyslope Avenue, a 2,018 sq. ft. residence reimagined for 2026. The heart of the home is a spectacular main-level Great Room bathed in natural light, where nearly every window frames expansive, breathtaking views of the Bay and Mountains. This airy space flows through a 16-foot stackable sliding door to a permitted two-level deck with modern cable railing, perfect for entertaining. The lower level features an intimate family room flanked by two bedroom suites, creating an ideal, private “zone” for older children or guests. Convenience is built-in with a dedicated inside laundry room with ample storage space. Every inch feels brand new, featuring 100% all-new electrical with designer recessed and flush-mount lighting, as well as all-new plumbing, gas lines, and central HVAC. Luxury defines the interior, from wide-plank European white oak floors and Level-5 drywall to a chefs kitchen with designer cabinetry and quartz counters. With three ensuite bedrooms, a private office, and custom-built bathroom vanities, this home offers the peace of mind of new construction with the character of an established Belmont setting.
