Margaret Harrington of Douglas Elliman holds the listing.

Here’s a look at the one-of-a-kind property.

A private island in New York is for sale for US$12.9 million.

The island, called Petre Island, is located in Carmel, New York, a little over an hour’s drive north of New York City.

Two houses designed by famous architect Frank Lloyd Wright sit on the property.

The island has been on and off the market and was previously listed for US$15 million in 2017.

The first house is the original 1950s guest house …

… and the other is a four-bedroom residence that juts out over Lake Mahopac.

A helipad on the roof of the main house makes the property “a quick helicopter ride from Manhattan or Westchester Airport”, the listing notes.

The house is built around a large rock.

The inside of the home is decorated in warm, earthy tones.

Stonework is scattered throughout the house, including in the modern kitchen.

Some of the bedrooms open up to balconies overlooking the lake.

Wooden shelving and storage are built into the home …

… and huge skylights let in plenty of natural light.

One section of the house extends out over the water and offers panoramic views of the lake.

Outside, expansive living areas allow alfresco dining …

… or warming yourself up by a fire in colder weather.

You will have the nearly 11 acres of the island all to yourself.

There is some controversy over the main house on the island.

According to Curbed, Frank Lloyd Wright designed a 5,000 square foot home for the island in 1950 but ended up building a small cottage instead, after the owner realised that he could not afford the larger one.

Years later, a new owner of the island had the original design built, but the Frank Lloyd Wright Foundation does not recognise it as an authentic Wright design.

Still, the geometric elements and blending with nature embody Wright’s designs. And the private island setting is a draw in itself.
