Several Long Island properties, including the original summer home of Ward Melville’s family in Old Field and an equestrian center in Old Bethpage, sold recently at auction.

The auctions, run by Maltz Auctions, took place at the company’s gallery in Central Islip. The Old Field home, which had an opening bid of $550,000, which included an additional undeveloped .7-acre parcel, received a high bid of $777,600.

“It was a vibrant environment with highly competitive bidding,” says Richard Maltz, president of Maltz Auctions.

The Old Field property — which had been owned by the family of Melville, a businessman and philanthropist active in the Three Village area, which consists of Setauket, Stony Brook and Old Field — has a six-bedroom, five-bathroom home, with winter views of Conscience Bay. The 2.78-acre property also has a guest cottage and watchtower. In addition, there is a vacant .7-acre waterfront lot with cabana and fixed dock.

The market value of the property was assessed at close to $1.4 million, according to Maltz Auctions.

The equestrian center, which received a high bid of $975,000, adjoins Bethpage State Park riding trails and the owner can pay for an annual permit to use state land as well as five miles of riding trails.
