John Phipps amassed almost of rolling Virginia farm lands in
The Plains, Virginia, including Brenton, an 1889 stone manor house. He was a
polo player and
Thoroughbred racehorse owner, and the property assembled from 1928 onwards would be the site of his Rockburn Stud farm. Upon his death it passed to his son Hubert. Phipps purchased an old
Quaker farm on
Long Island where he built a large mansion with magnificent gardens that, following his death, became a non-profit organization that today is known as
Old Westbury Gardens and is open to the public. In the 1920s he purchased several large properties in
West Palm Beach, Florida, including one that was once used as a pineapple plantation. He subdivided the property and turned it into the three largest subdivisions containing luxury residential homes in what is now the
El Cid Historic District. John Phipps built a home for himself he called "Casa Bendita." A large oceanfront mansion in Palm Beach, Florida, it was designed in 1921 by architect
Addison Mizner. Today, the property is occupied by his granddaughter, Susan Phipps Cochran, and her husband. ==Personal life==
