6The Hydropolis, Dubai
Situated 66 feet underwater, in the Persual Gulf, the Hydropolis Underwater Hotel and Resort is definitely a futuristic hotel.
Located in Dubai, the underwater hotel will cover an area of 260 hectares, the equivalent in area to Hyde Park in London. So you can compare these 2.
Its design was created by Professor Roland Dieterle and Joachim Haused and is planned to be composed of 3 sections: a land station, a connecting train and the underwater hotel, which looks like a jellyfish.
The construction cost for this futuristic hotel is around $804 million, and it will offer 200 fancy rooms.
