27 Rainier Circle Gracefully positioned on a prominent corner homesite within the coveted Woods of South Barrington, Rainier House is a timeless brick and stone residence defined by exceptional craftsmanship, refined architectural detail, and a remarkable collection of improvements completed well beyond its original construction. Framed by professionally designed landscaping and filled with natural light, the home offers generous proportions and an effortless balance of elegance and everyday comfort. A sweeping bridal staircase creates a memorable arrival, while rich millwork, picture molding, shadowboxing, substantial crown molding, and thoughtfully selected finishes lend warmth and character throughout. Designed for gathering, the Palladian kitchen is appointed with a built-in refrigerator, wine refrigerator, warming drawer, expansive pantry, and abundant workspace, opening seamlessly to the family room where a floor-to-ceiling stone fireplace and coffered ceiling create a striking architectural focal point. A library or flex room with custom built-ins, dual laundry rooms, a beautifully organized mudroom, integrated Sonos audio, designer lighting, and custom Hunter Douglas plantation shutters and power shades reflect a home where beauty and function exist in equal measure. Upstairs, each generously proportioned bedroom is filled with natural light and enjoys the privacy of its own ensuite bath. The primary suite unfolds with a welcoming sitting area before opening into a serene bedroom with a coffered ceiling, custom walk-in closet, and a beautifully appointed ensuite bath. Beyond the interiors, the outdoor living spaces are designed as a true extension of the home. An expansive paver terrace with a pergola, gas fire pit, tranquil pondless water feature, and a fully equipped outdoor kitchen featuring a built-in Wolf grill, side burner, outdoor refrigerator, DCS stainless steel cabinetry, limestone bar, integrated speakers, and architectural landscape lighting creates an effortless setting for entertaining throughout the seasons. Completing the residence is an oversized four-car garage with epoxy flooring, custom cabinetry, overhead storage, insulated steel smart garage doors, a deep-pour basement with exterior walk-up access and rough-in for a future bath, upgraded dual tankless water heaters, enhanced irrigation, battery-backup sump pump, and infrastructure improvements that reflect the exceptional care with which the home has been maintained.
