20 Villa Coublay
Frontenac, MO, 63131
Once upon a time on Villa Coublay, a classic brick ranch decided it was ready for its next chapter. A whole home renovation and a two story addition later, it lives as new, with an effective year built of 2021 and more than 4,600 finished square feet on the main level alone. Double front doors open to wide plank hardwood, vaulted ceilings and black framed windows filled with trees. The kitchen gathers everyone at a long island, with double wall ovens, a built in refrigerator, wine storage and a sink set beneath a wall of windows overlooking the yard. The family room is wrapped in windows and afternoon light. The addition now houses a primary wing with a separate den, a generous walk in closet with its own washer and dryer, and an expansive bath with a freestanding tub, a walk in glass shower with bench and a morning beverage bar. Three additional bedroom suites complete the main level. Below, a deep pour lower level offers added ceiling height and waits for its next owner to write the final chapter. All of this sits on one acre in the heart of Frontenac, in the Ladue School District.
