Beautifully updated 1.5-story home in the heart of Des Peres offering 3 bedrooms, 2 full and 2 half baths, a desirable main-floor primary suite, and an impressive list of improvements. A comprehensive first-floor renovation completed in 2019, designed by architect Scott Volding and completed by Shackelford Custom Homes, transformed the home with thoughtful design, quality finishes, and comfortable spaces for everyday living and entertaining. Hardwood floors, extensive millwork, and abundant natural light welcome you inside. The beautifully renovated kitchen features crisp cabinetry, stone countertops, stainless appliances, generous workspace and storage, plus a large center island with seating. The kitchen flows into the inviting family room, where a painted brick fireplace creates a warm focal point. The adjoining sunroom offers another light-filled, flexible space for relaxing or dining. The spacious first-floor primary suite features a beautifully updated bath with dual vanities, a large walk-in shower, stylish tile flooring, and access to a well-designed closet area. A half bath serves the main level, while a dedicated office provides an ideal work-from-home space and includes hookups for optional main-floor laundry. Upstairs you’ll find two additional bedrooms and a full bath, providing privacy for family or guests. The lower level offers additional living and recreation possibilities with updated flooring and an upgraded half bath. The extensive 2019 improvements included a new roof, gutters and downspouts, windows and doors, extended rear patio, front sidewalk, retaining wall, tuckpointing of the brick exterior and chimney, AprilAire humidifier, lower-level flooring and bath upgrades, and main-floor laundry hookups. Additional improvements include a Mitsubishi mini-split HVAC system for the family room/sunroom in 2020; new shed, front-yard irrigation, landscape lighting, and water heater in 2021; and new sunroom windows and microwave drawer in August 2026. Outside, mature trees, established landscaping, and a spacious lawn frame the classic brick-and-siding exterior, while the extended rear patio provides an inviting spot for outdoor dining and entertaining.
