A four-acre complex in Sagaponack is home to four separate structures, including one dating back to the 19th century. It is on the market for $17.95 million.

A wooden barn — built in the 1880s, moved from a property down the street and renovated and expanded over the years — serves as the main house, with three bedrooms and five bathrooms. It features antique brick and vintage wood flooring, and a master wing that has a sitting room with a fireplace and a private terrace.

A 1930s farmhouse with a wraparound porch — a Sears and Roebuck kit house, says listing agent Gary DePersia of The Corcoran Group — serves as a six-bedroom guesthouse. A separate barn was transformed into a gym and pool house with a full bathroom. There is also a two-car carriage house, with an artist’s studio and full bath above, while a chicken coop on the property is used as an office.

The property also includes a 45-foot gunite pool, a sunken tennis court and pond with a red wooden bridge.
