204 Old Mill Rd, Greenwich, CT 06831
About this home
The grand courtyard approached by a sweeping tree-lined drive leads to this stone and shingle masterpiece built by a premier builder known for extraordinary craftsmanship. The architectural details and exquisite millwork throughout the wonderfully proportioned interior spaces include extra ceiling height-incorporating reclaimed beams and natural oak coffered designs, high oak wainscotting in public rooms, three dramatic floating staircases, five custom fireplaces, a limestone front to back foyer with French doors, and 5'' hardwood floors. The showstopper is the one-of-a-kind kitchen/family room space that is unique in both size and openness, and features abundant cabinetry, a massive granite island, high-end appliances, a floor to ceiling stone fireplace and walls of glass with a view of the lush, 4 acre grounds, pool, spa and outdoor entertainment patio areas. The outstanding quality continues upstairs with a spectacular primary suite boasting two sitting rooms, two luxury bathrooms, two walk-in closets/dressing rooms and marble fireplace. Four very large en-suite bedrooms, family room, study area, laundry room and studio space over the garage complete the 2nd floor. The approx 4500 sq ft lower level with 13 ft ceilings has it all - multifunctional recreational areas, theater, gym, dance studio and vast storage/utility areas. Exceptional country estate on a quiet lane off Round Hill Road and only 10 minutes to downtown Greenwich.
