Updated 31h ago

The result of a masterfully executed, comprehensive transformation, this property functions as a virtually new, private modern estate in the heart of Frontenac within the Ladue School District. With architectural and design contributions from Space Architects, Palermo Group, and Pooltron, alongside custom execution by Artizan Builders, the property reflects an exceptional standard of craftsmanship, sophisticated entertaining, and seamless indoor-outdoor living. Positioned at a premium elevation within the neighborhood yet engineered for effortless single-level living, the estate offers 6,499 square feet of finished main-level interiors between the 4,690-square-foot primary residence and the 1,809-square-foot pool house. More than 5,500 square feet of finished outdoor living space—including the expansive open-air terraces and the custom gunite pool—extend directly beyond, establishing an extraordinary 12,000-square-foot continuous entertaining environment across a single main-level footprint—with the scale, privacy, and amenities of a private resort. Defined by an uncompromising level of investment, virtually every surface, system, and architectural detail has been executed to an extraordinary standard. An extensive collection of custom appointments, curated materials, and highly considered design elements underscores the remarkable depth of this investment. Far beyond a conventional renovation, this is a comprehensive reinvention of the property—an exceptionally rare, move-in-ready modern compound offering a caliber of design, construction, and resort-level living seldom available in Frontenac’s premier corridor.
