What do you get when you take a 10,300-square-foot main house set on 11.2 waterfront acres complete with rolling lawns and Atlantic Ocean views, and add a a guest house, pool, tennis court and clubhouse?

You get “Briar Patch,” the estate at 90 & 100 Briar Patch Road in East Hampton listed for sale for $140 million.

Known as the “Shepard Krech House,” it was designed by architect Arthur C. Jackson and built in 1931, then completely remodeled in 1990 by architect-to-the-stars Peter Marino. It’s the most expensive single-family home for sale in all of New York state, and the second-priciest home listed in the entire nation. Only the Palazzo di Amore in Beverly Hills — listed for $195 million — tops this Hamptons’ beauty. In New York City, the current priciest listing is the $120M Safra family townhouse.

This Georgian Revival house is in keeping with the characteristics when it comes to upper-crust style and furnishings. The 6 bedroom-home is spread over three stories and includes a sunken library, gourmet kitchen and a gym.

The second residence was designed by Marino and built in 1990, adding four bedrooms and a gourmet kitchen to the property. But for all the wondrous proportions and materials used to create the main and guest residences, Briar Patch earns its reputation as one of the finest single-family properties in the country due to its audacious setting on Georgica Pond, a large, saltwater lagoon perfect for paddleboarding, kayaking and canoeing.

The Hamptons have long been the exclusive playground of the entertainment and Wall Street crowds, so it’s not unusual to see properties valued at $50 million or more. However, given the acreage and the fact that the property is already legally subdivided into two separate parcels (7.5 acres and  3.7 acres) suggests a new owner could spin off one of the parcels to recoup some capital.

The grounds are simply sensational, if you like open lawns and mature trees lining your ocean-view stomping grounds. The sight of swans, egrets and herons are technically free of charge. However, these native birds probably look better when spied from such a pricy estate as Briar Patch.
