Architect Koen Othuis of the Netherlands specializes in "amphibious" buildings, some floating and some using other systems to adapt to wet environments.
[2] In 2010 Architect Sarly Adre Sarkum of Malaysia from architecture firm SA Squared or Sarly Adre Sarkum Architecture[3] proposed a building about the size of the Empire State Building which would float in the ocean with only the top few stories out of water.

Seascrapers will be located where deep sea current is adequate for the production of power, for example, the Gulf Stream.
The concave shape of the seascraper not only allows light to penetrate to the lower levels, but collects and processes rainwater..."
