Tucked atop a rolling hill and surrounded by 3.6 acres of mature oak trees, this one-of-a-kind custom brick ranch offers a rare combination of space, privacy, and proximity to downtown St. Charles. With more than 6,300 square feet of finished living area, the home feels both expansive and inviting, enhanced by walls of windows that draw in abundant daylight and showcase the natural setting from nearly every angle. Freshly painted throughout and featuring newly refinished oak flooring on the main level in 2025, the interior presents a crisp, updated aesthetic while preserving its timeless character.    Three generously sized bedroom suites are located on the main level, providing comfortable and private accommodations. The kitchen is a true centerpiece, outfitted with thick quartz countertops and a suite of high-end appliances including Sub-Zero refrigeration and freezer drawers, Miele cooking and cleaning appliances, a built-in espresso system, and a beverage center, all designed for both everyday use and entertaining. The central living space is anchored by a full masonry fireplace with custom built-ins, creating a warm and welcoming environment. A spacious mudroom with pantry and a main-floor laundry area add to the home's thoughtful functionality.    The finished basement offers exceptional flexibility with a recreation area, lounge space, full bathroom, fourth bedroom, generous storage, and a second laundry room. Outdoor living is equally impressive, featuring a bluestone patio with integrated grilling station, natural gas fire feature, and pergola, ideal for hosting or quiet evenings outdoors. A 32x20 barn equipped with water, electricity, and an overhead door provides ideal storage for vehicles, equipment, or hobbies.    Notable upgrades include a Generac whole-house generator, programmable Lutron lighting, Trane climate controls, power shades, and energy-efficient LED lighting. The home underwent a complete renovation down to the framing in 2018, which included a new roof, expanded footprint, three HVAC systems, and all new plumbing, with a new driveway added in 2022. Newer sediment filter installed. This exceptional property offers refined living, modern infrastructure, and a truly serene setting.
