From this elevated vantage point, enjoy exceptional views of the historic downtown skyline and the iconic church steeple from every window. The lower level adds even more flexibility with a finished space ideal for a home gym or a cozy lounge. Practicality meets luxury with a one-car garage plus an additional assigned parking space within the gated driveway.
