Lightning Tree Farm, the Millbrook, New York estate of Johnson & Johnson heiress Elizabeth Ross “Libet” Johnson, was listed in October 2016 for $28.5 million, which would have been a record for Millbrook. The estate has more than 600 acres, an 1850 Greek Revival main house of 18,000 square feet with nine bedrooms, four guest houses and a grass helipad. It has since been subdivided and re-offered in parts.

What happened to the Millbrook mansion?
Johnson bought the property around 1980 and later expanded it by buying neighboring land. The 2016 listing priced the whole estate at $28.5 million, and the listing agent said a sale at that figure would set a record for Millbrook, where the highest price paid for a house in the village had been $18.75 million.
In 2019, the family subdivided the property and held on to some parcels. Listing coverage at the time reported a 373-acre parcel with the main house offered at $12.995 million, along with smaller lots of 57 acres at $900,000 and 46 acres at $850,000. We could not find a confirmed closing price for any parcel, so these are asking prices, not sale prices.
What is inside the estate?
The main house
The main house was built in 1850 in the Greek Revival style. It measures 18,000 square feet and has nine bedrooms. The interiors have 18th-century-style craftsmanship, intricate molding and a spiral staircase in the entry hall. The dining room is known for its aqua wallpaper and pink chairs, and there is also a library, a ballroom, a movie theater and an elevator.
The grounds
The property has more than 600 acres of rolling hills, statues, stone urns, ivy-covered walls and a reflecting pool at the north end. A limestone swimming pool has pool houses and a changing space around it. A private grass helipad lets you arrive by helicopter, which is a rare feature for a private home.
The horse facilities
A stable has room for around 20 horses, and there is a riding arena. The family has other homes and no longer used this part of the estate in 2016, but kept one of its working farms in the neighborhood.
