Private island home being built off the coast of New York

SNY:

A few months ago, I had to charter a boat to take scout pictures of Davids Island, located in Long Island Sound off the coast of New Rochelle. As we were curving around the southern side of the island, I noticed something in the distance…

A squat, one-story structure on its own private island.

Though it seemed dilapidated and possibly abandoned from a distance, as we drew closer, I began to see signs of modern activity: a huge solar panel on the roof, along with construction equipment scattered about. My guide explained that this is Columbia Island, and that the owner is currently converting the building into what will be the only private island home off the coast of New York City.
