Custom Granite Bay estate tucked at the end of a private cul-de-sac in desirable Grosvenor Downs. This beautifully maintained home combines impressive architectural detail with a highly functional floor plan designed for everyday living, entertaining and multi-generational flexibility. A dramatic two-story foyer introduces boxed-beam ceilings, extensive millwork and a sweeping wrought-iron staircase with brass handrail. The downstairs primary suite offers privacy from the main living areas, French doors with a beveled-glass transom, a recently remodeled bath and an oversized walk-in closet with custom built-ins. The updated kitchen features JennAir appliances, a generous walk-in pantry and an adjoining butler's pantry/catering station with extensive cabinetry, granite counters, sink, wine refrigerator, warming drawer and electric burners. A spacious breakfast area with built-in hutch overlooks the backyard. Upstairs, a large open game and entertainment room provides space for a pool table and includes a wet bar and built-in cabinetry. Three additional bedrooms include a second primary suite, plus a bedroom currently arranged as an office with built-in desk, shelving and Murphy bed. Exceptional storage includes a large walk-in attic. Recent improvements include updated HVAC systems, tankless water heating, Ecobee controls, whole-house fan and extensive LED lighting. The private, tree-lined backyard is accessible from the kitchen, family room and downstairs primary suite and is designed for outdoor living with a Pebble Tec pool and spa, rock waterfalls, and newer outdoor kitchen and bar. The expansive driveway leads to a side-entry 3-car garage, plus gated RV access. Raised garden beds and fruit-bearing trees complete the grounds. All of this in an established Granite Bay neighborhood just minutes from Folsom Lake, shopping, dining and recreation.
