A converted barn that once was part of the notorious Woodward estate is on the market for $1.75 million in Oyster Bay Cove.

The four-bedroom, 4.5-bathroom Colonial was built in 1913 and was originally owned by the Woodward family, says owner Mandy Laderer, an agent with Douglas Elliman Real Estate and listing agent for the house.

William Woodward Jr., heir to the Central-Hanover Bank of New York fortune, was shot dead by his wife, Ann, in their mansion in 1955 when she allegedly believed that he was an intruder. Dominick Dunne based his novel "The Two Mrs. Grenvilles" on the case. It was later made into a TV movie.

The property was subdivided, and in 1957, Laderer says, previous owners converted the barn into a house. She moved into the home in 2005, and did a major renovation.

"When I bought it, it was tattered and tired inside," she says.

Now, the 5,500-square-foot home has a 30-foot entrance to a bridal staircase that leads to an 800-square-foot master suite complete with 25-foot ceilings.

"We kept the integrity of the barn -- the stalls, the doors, the courtyard, the soaring ceilings," Laderer says.

Laderer also says she decided to give each room a party atmosphere, adding a pub room, a media room and a gym to the home.

The landscaped backyard comes with a pool and a root cellar.
