A bold set of designs have been floated for an outrageous man-made, private island.

Featuring a penthouse, jungle deck with a waterfall and an alfresco dining area, it would be the first in the world to move under its own power.

Owners of the island would be treated to 360-degree views within the penthouse, accessible by an 80-metre elevator.

Around the complex, residents would find all the amenities expected on a land-based tropical getaway — including a spa, gym, beauty salons, bar and pool.

The inclusion of vertical gardens, palm trees and even a shark-feeding station add more natural elements to the nautical island.

Designers at Migaloo Private Submersible Yachts put together the plans, which the company insist could be built in the near future.

Based on technology that Migaloo have available, the company say the movable paradise — known as Kokomo Ailand — would also be perfect for a high-class hotel, company headquarters or casino.

Were the island to be used for commercial purposes, space for crew members to live has been included, as well as a helipad for easy access.

All islands will be tailored to the client’s needs, the company said.

 “The response has been amazing,” Christian Gumpold, managing director of Migaloo Private Submersible Yachts, said.

“We are currently negotiating with several clients who are very interested in the project.

“We developed an initial design concept to show our ideas and the main design direction.

“Our design team needed some months for this, but the actual details in the design — depending on the client’s wishes — will be a much longer and intense process.

 “This is common in the yachting industry.

“Living on and with the sea will be a future mega trend, and this island can be a first step to adapt to this new way of living — combined with our submarines, it will be a perfect match.”
