The two islands sit .2 nautical miles from each other and are for sale for a collective $13 million.
Columbia Island was built in the 1940s by CBS to house a radio transmitter. Before the current owner purchased the Island, it was owned by the College of New Rochelle and used for marine biology studies.
Columbia Island, the smaller island of the two, has a fully renovated four-bedroom, two-bathroom, 5,625-square-foot home.
The island is completely self-sustaining. The two solar panels on the roof generate enough power to operate the house.
A reverse osmosis desalination system turns the seawater around the island into fresh, usable water for the home.
A lower-level media room with exposed brick wall sits parallel to the large living space.
An open floor plan connects the living space to the kitchen, which can be seen in the background of the photo below.
The open kitchen is newly renovated with stainless-steel countertops.

The home includes two 50kW backup generators and a blast and fire-resistant door to protect the machinery.
The home comes with a boat and a barge.
Pea Island can be seen from the rooftop on Columbia Island. Pea Island spans nearly five acres and includes an open beach and an abundance of indigenous plants.
The house, according to Bloomberg, is nearly hurricane-proof, with a five-foot thick, 14-foot-tall seawall.
