In 1965, the 16-acre Glen Alpin estate was purchased for $100,000 by Christopher DeCarlo, a real estate developer from Newark. He announced he was going to restore the mansion and original gardens. Instead, he made his own changes.
On the east side of the house, DeCarlo enclosed the area between the laundry building and the kitchen and added another room in front of the laundry building that was used as a caretaker’s apartment between 1964 and the 1990s. The porch on the west side of the house was removed in the 1980’s. He also removed the balcony over the front portico, and replaced the wood columns of the front portico with wrought-iron supports. Sometime after the late 1970s, DeCarlo painted the puddingstone white.
Inside, DeCarlo modernized the bathrooms and the kitchen. He installed a sauna off one of the upstairs bedrooms adjacent to the servants’ quarters. Rounding out the changes, he painted some of the paneling on the first floor and stained some of the floors black, but the stain was reversed while DeCarlo still owned the property.
DeCarlo subdivided the property in 1970. Unfortunately, the formal gardens and a portion of the original driveway were included in the new parcel and taken away from the Glen Alpin house. DeCarlo built a new house on the subdivided lot, in which he lived, while he retained ownership of the Glen Alpin property.
In the mid 1990s, DeCarlo tried to obtain permission from the Harding Township Planning Board and then the Board of Adjustment to allow Glen Alpin to be used as a chapel for an interfaith church. The permission was never granted, and DeCarlo eventually withdrew his request.
The next owners, Liang-Bin Jean and Su-Hsiang Jean, acquired the new house and gardens from DeCarlo in December 1999, and acquired Glen Alpin in April 2002.
