Old Westbury Gardens-Phipps, John S., Estate (Boundary Increase)

Old Westbury Gardens occupies 187 acres in the Village of Old Westbury, New York, and preserves the remaining core of the country estate of John S. and Margarita Grace Phipps. Westbury House, a red brick mansion with limestone details and a Collyweston stone slate roof, was built in 1906-1907 on the highest point of the property. George A. Crawley designed both the house and its grounds, grading the land and laying out long allées of lindens, beeches and hemlock, along with a Walled Garden, ponds and a pool area. Later alterations to the house were made by architects including Horace Trumbauer, who extended the Red Ballroom in 1919. The estate is significant for landscape architecture, reflecting a unified plan of house and gardens in the manner of an English park. This boundary increase adds acreage acquired since the first listing, along with fuller descriptions of the gardens, outbuildings and landscape features. The property is now run as a museum and public garden.
