Hydropolis Underwater Hotel and Resort
Dubai, hotel hydropolis is the first luxury hotel in the world under the sea. Which includes three elements: a land station, where guests are greeted, connecting tunnels, which will transport people by train to the main hotel area, and 220 suites within the submarine recreation complex. Equipped with concrete and iron, plexiglas walls and curved roofs will allow guests to see fish and other sea creatures. This hotel is considered a 10-star hotel. there are only a few locations in the world where such lofty dreams can be realized. Most of today's architectural wonders are embodying such a fantastic mirage of the desert.
The concept of ground hydropolis station
In order to enter the real space, visitors will start on the ground station. These 120m woven, semicircular cylinders will be arched over the building graded. At the lowest level the passenger board of the voice train is driven by a cable fully automated along the guideway, standalone modular steel for hydropolis.
On time and on-demand systems will facilitate the efficient supply of goods logistics to the hotel. The top floor of the ground station houses various facilities, including a cosmetic surgery clinic,a marine biology research laboratory and conference facilities. 
At a lower level are staff rooms, storage of goods and loading areas, and hotels and parking area. Land stations also include restaurant cinema and high-tech filtering the evolution of life in the ocean and the history of underwater architecture.
As a final, the screen will open to reveal the real life of hydropolis. The viewing platform at the front opening of the enclosed roof will allow the view architecture and show light from the hydropolis.
Underwater design concept
the concept of hydropolis developed from hauser, a passion for water and sea, and goes much more than just building an underwater hotel. More than just curiosity, it is a commitment to philosophy beyond its reach. "once you start digging deeper and deeper into the subject, you can not resist the sense of being fascinated and you begin to care about all the related issues," he explains. "The human is made up of 80% water, the earth is made up of 80% water, there is life. " Hydropolis reproduces human organisms in architectural design. There is a direct analogy between human physiology and architecture. The geometric element is the number eight lying on its side and written in a circle. Space created in basins will contain function areas, such as restaurant, bar, meeting room and suitetema. This can be compared to the components of the human organism: motor function and the nervous and cardiac system, with the central sinus node representing the pulse of all life.
The ballroom, located at the center of the nerve, will have an asymmetrical pathway connecting different floors along the floor. A roof, pulling out such large petals would allow staging the celestial event open. Stairs, elevators and ramps will provide access to the ballroom, while flanking the catering area will provide banquets and receptions.
