Water Discus Underwater Hotel Concept, Dubai, United Arab Emirates

A long-awaited undersea hotel in Dubai looks finally set to be built, after an agreement to develop it was unveiled this week. The Water Discus Hotel won't be totally submerged as previous plans have suggested, but will be a disc-like structure with part of the building above water and the rest below the surface.
The 21 rooms are expected to be submerged up to ten meters below the surface of the water, with huge windows offering a view out from the bed and an external 'explorer' robot which can be controlled from the room to allow guests to interact with marine life.
