OPEN HOUSE CANCELED due to PENDING status. Welcome to this custom-built, one-owner ranch home nestled on a tranquil cul-de-sac in Town & Country. This residence, meticulously maintained and thoughtfully updated, offers sophisticated living on a private, nearly three-quarter-acre wooded lot with a custom saltwater pool. Step inside and be captivated by the vaulted great room, where a floor-to-ceiling stone fireplace serves as a dramatic centerpiece. This space flows effortlessly into an updated kitchen and breakfast room with direct access to the sparkling pool. A den with a wet bar and built-in bookcases provides a quiet retreat, while the vaulted sunroom with cozy gas fireplace and tongue-and-groove ceiling opens to a private deck and pool area.This residence features a smart layout with 5 bedrooms and 3.5 bathrooms. The main level hosts the primary suite and three secondary bedrooms. The finished, walk-out lower level provides additional living space with a rec room, fifth bedroom, a full bathroom, and ample storage—making it an ideal space for guests, a home gym, or a dedicated entertainment area. The large saltwater pool includes an elevated lounge platform with a custom water feature. An attached two-car garage and main-level laundry room add to the home’s convenience. Significant recent updates, including the roof, many of the home’s mechanics, and the pool's foundation and liner, offer peace of mind. This is more than a home; it's a lifestyle waiting for you to enjoy.
