Daisy Buchanan has mixed her last drink.

The dramatic but dilapidated Sands Point mansion that some F. Scott Fitzgerald scholars believe served as inspiration for portions of “The Great Gatsby” will soon be reduced to rubble.

The owners of Lands End, a 25-room colonial mansion that sits in grand isolation above Long Island Sound, plan to raze the structure to make way for a five-lot subdivision, each with a $10 million home, according to Sands Point Village Clerk Randy Bond. Some Fitzgerald enthusiasts point to the 1902 residence as the template for Daisy Buchanan’s home.

“I think it’s probable that he used the physical aspects of Lands End as a model,” said Professor Ruth Prigozy of Hofstra University, a noted Fitzgerald specialist. “It was the view — that’s what set it apart.”

Pace professor Walter Raubichek said that no one can be sure of Lands End’s claim to fame.

“It’s certainly possible,” he said. “But Fitzgerald never made any direct statement about it. Because he knew that area well, there are a few homes that people sometimes think could have served as an inspiration.”

The current owners believe that its pedigree has been overstated. “To be honest with you there isn’t anything really special about it,” said David Brodsky, who along with his father bought the property for $17.5 million in 2004 from Virginia Payson, the late wife of former Mets owner Charles Payson.

“We did a lot of research on its history and there is really no evidence that Fitzgerald was even ever there,” he said.

He also doubted that famed architect Stanford White designed it. “I think a lot of people there just want to be able to say they live near the Gatsby home,” he said, adding that his father, Bert Brodsky, had initially hoped to carve a family compound out of the property but found the home beyond repair.
