Splendor in September Designer Showhouse set to benefit Morristown Medical Center


The Woman’s Association of Morristown Medical Center (WAMMC) said Tyvan Hill in the New Vernon section of Harding Township, N.J., will be the site of its 19th Designer Showhouse and Gardens, the signature fundraiser of WAMMC.

Formerly known as “Mansion in May,” the event is rescheduled from May and now titled “Splendor in September.” Funds raised will benefit the expansion of the Gagnon Cardiovascular Institute at Morristown Medical Center.

The showhouse will be open to the public daily Sept. 8 through Oct. 4, starting at 10 a.m. Tickets are available for a given date and time and must be purchased in advance at

All state and local COVID-19 requirements will be followed. Masks must be worn throughout the house, social distancing will be enforced, the number of visitors in the house will be limited. Meals will not be available. Instead some snacks can be purchased in a small tent, where chairs will not be used.

Fifty designers and landscape architects will transform the 1920s country estate into a place of its former glory. The house was designed by the New York architectural firm of Peabody, Wilson & Brown for John Wesley Castles, Jr. and his wife, Dorothea Bradford Smith, between 1928 and 1929.

Castles was a New York lawyer and an investment banker who served in the U.S. Army in both World War I and World War II; his wife was a daughter of the former Vermont Governor Edward Curtis Smith and granddaughter of J. Gregory Smith, governor of Vermont during the Civil War.
