Property Description
An allée of majestic magnolia trees underplanted with sculpted boxwoods lines a white-pebble drive leading to one of Greenwich's most iconic Great Estates. Inspired by the grandeur of Newport's Gilded Age mansions and transformed through an extensive four-year renovation, this exceptional residence masterfully balances historic character with modern functionality. The result is a rare offering where architectural significance, luxurious comfort, and enchanting surroundings converge. Interiors designed by Mar Silver allow for entertaining on a grand scale or intimate family gatherings alike. Each room has been thoughtfully curated, revealing a new delight around every corner. The estate grounds, designed by renowned landscape architect, James Doyle, feature his signature European-inspired gardens, as well as a 3-bedroom guest house, and oversized swimming pool creating a private compound of extraordinary beauty and distinction. This remarkable property is located on prestigious Round Hill Road, only 10 mins to downtown Greenwich and 45 mins to Manhattan.
