This property in the Southampton Estate section is made up of two parcels that are nearly 2 acres each. The nearly four-acre property, surrounded by high hedges, is on the market for $19.9 million.

The property, which includes a six-bedroom house with a pool, has been in the same family for a number of years, and the size is rare for the area, says the listing agent.

"The average lot size in the Estate section is 2 acres and this is double," says Harald Grant of Sotheby's International Realty, who is marketing the property. "It's beautifully landscaped and very special."

The layout of the house includes a great room, and it has an open floor plan. The great room and the master suite have fireplaces, and both rooms, as well as a guest suite and a media room, open to a deck in the back of the property.

A heated gunite pool and an all-weather tennis court round out the developed half of the property. Both parts of the property have several mature trees.
