Nestled on a quiet cul-de-sac in coveted Frontenac and within the Ladue School District, 5 Outer Ladue offers timeless architecture, generous living spaces, and an exceptional setting on a flat, private one-acre lot. Soaring 10-foot ceilings and floor-to-ceiling windows fill the main level with natural light. A gracious foyer opens to spacious formal living and dining rooms, while the expansive kitchen features a large center island, abundant workspace, and beautiful views of the backyard and pool. The adjoining breakfast room flows into a warm and inviting hearth room with a gas fireplace and built-in bookcases. The main-floor primary suite is thoughtfully positioned for privacy and features a spacious bath with dual vanities, jetted tub, separate shower, and walk-in closet. A main-level laundry room and half bath are conveniently located just off the three-car garage and offer easy access for poolside guests. Upstairs, one bedroom features an ensuite bath, while two additional bedrooms share a dual-access bath. The finished lower level adds even more flexibility with a bedroom, newer full bath, expansive recreation space, and abundant storage. Outside, a terrace overlooks the sparkling pool and lush landscaping, while the expansive level yard offers plenty of room for entertaining, recreation, and play. With its desirable floor plan, exceptional outdoor spaces, and prime Frontenac location, this special property offers a wonderful opportunity to enjoy now while updating and personalizing over time.
