Dubai has always been a city with a strong maritime heritage that today is transformed by massive waterfront developments. The inspiration for this project came from the relation of the sea and the city. Conceived as a continuation and a transition through the wide public space, the building dives into the ocean and merges with it. The experience evokes a descent to the seabed. The museum is an artificial underwater environment organized under an immense glass roof, designed to give the maximum view of the ocean and intensify the feeling of diving into the seabed. Interior space is organised through cascading platforms that develop in a successive and continuous manner, allowing a panoramic overview of the whole interior. Water functions as a temperature buffer for the building simulating the ocean's role as a regulator of the world climate.
