In 2007 when Al Sutton was in his 70s, he purchased Columbia Island, which is a 30-minute boat ride from Manhattan, New York, for just $1.4 million.

A few years later he purchased the neighbouring Pea Island for $717,425 and now, 12 years later, Sutton is ready to move on, he told Bloomberg.

Now, Sutton’s listed Columbia island, which hosts his 530 square metre holiday home, on William Pitt Sotheby’s International Realty for a whopping $18.6 million.

The island residence is self-sustaining, with solar panels on the roof for energy, a desalination machine to provide clean water, and a septic system maintained by a private service.

Sutton also installed a 4-metre high concrete sea wall that’s 1.5-metres thick, as well as automatic storm shutters and a pumping system in the basement that can handle 60,000 gallons of water per hour, CNN reported.

Once a 500-square metre bunker and the base of a 120-metre broadcast tower, the island’s now-home boasts four bedrooms, two bathrooms and is equipped with a gourmet professional kitchen.
