Plans are afoot to build a semi-submerged extravagant resort project on the Qatar coast, that will cost a massive $500 million.

The Amphibious 1000, which will be built in the middle of a marine reserve, is designed by the Italian firm Giancarlo Zema Design Group, according to news.com.au.

The project will feature both land and sea developments including four giant hotels with underwater rooms that resemble super-yachts.

There will also be 80 “jellyfish” self-contained floating suites, with each having four floors and an underwater “aquarium lounge”.

Hydrogen-powered 20 metre aluminium yachts with underwater viewing areas will transport guests around the resort.

It will extend horizontally for one kilometre and it has a striking similarity to Dubai’s Palm Island.

“It is like a big aquatic animal stretching out from the land into the sea and extends horizontally for one kilometre thanks to two long wide arms,” Giancarlo Zema said.

On land there will be a museum, floating walkways, a restaurant with panoramic views, exhibitions, aquariums and a glass tunnel that will lead to the underwater observatory in the centre of the marine park.

The resort is designed to be “in harmony with nature”.
