Gleaming hardwood floors and recessed lighting abound. A main-floor full bath with shower flows from an adjacent, separate laundry room with entry from the connected two-car garage. A dramatic, curvilinear staircase leads to the second level with wrap-around oak railings and breathtaking vistas of the private forest and brook in all seasons. Retreat to the primary bedroom suite that offers dual walk-in closets, an additional wall of closets, a separate windowed home office, a king-size bedroom, and an ensuite spa-style bath equipped with double sinks, a large storage vanity, a jetted tub, and a separate shower.
