William Pitt and Julia B. Fee Sotheby's International Realty

For $13 million you can own two private islands that are just 30 minutes from Manhattan by boat.

Pea and Columbia Islands sit .2 nautical miles apart on the Long Island Sound in New Rochelle.

The current owner fully renovated the 5,625-square-foot home on Columbia Island, which includes four bedrooms, two baths, an open kitchen, a lower-level media room, a boat, and a barge, listing agent Patti Anderson told Business Insider.

Anderson also confirmed to Business Insider that the home is completely self-sustaining. On the roof are two independent solar panels that generate enough energy to operate the house, while a Reverse Osmosis Desalination system turns the seawater around the island into fresh, drinkable water.

Pea Island has been left in its natural state and spans nearly five acres. It includes an open beach and an abundance of indigenous plants.

Take a look at the two islands below.

Pea Island and Columbia Island are about 30 minutes from Lower Manhattan by boat.

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.

The current owner spent nearly a decade renovating it and installed windows, wiring, and walls with corrosive-resistant materials to protect the home from water and storms.

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.
