Description

Your next chapter…a lot more lifestyle! Just steps from the lake and conveniently situated off Lake Saint Louis Boulevard, 4030 Key Harbour Drive is a destination unto itself. Thoughtfully curated interiors and inviting entertaining spaces flow into an extraordinary outdoor oasis through a four-season room, private terraces, and covered and open-air patios. The home’s vintage of 1996 has been beautifully modernized with refined finishes and exceptional amenities. Twelve-foot ceilings and expansive gathering spaces lend scale to the main level and high design throughout offers sophisticated entertaining. A chef’s kitchen appointed with Wolf and Sub-Zero appliances, a striking stone hearth fireplace, a light-filled four-season room and a dedicated office enrich everyday living. The primary suite offers a private terrace, custom walk-in closet and a spa-inspired bath with heated floors, dual vanities, and a wet room featuring a steam shower and jetted tub. The lower level extends the home’s hospitality with an open family room, dining area and kitchen. Three additional bedrooms, two bathrooms and access to private patios offer flexibility for guests or multigenerational living. Beyond the French doors, meandering stone paths unfold into a remarkable landscape designed for recreation and repose. A resort-style pool framed by dramatic boulders and cascading waterfalls anchors the setting, complemented by a sport court, firepit lounge and a lovely garden walk. A three-car smart garage, circular drive and motor court complete the property. If having it all is what you want, look no further! Showings begin Thursday, 11/5/26. Open House Sunday 11/8/26 1-3!
