The tower with its skin acting as a structural element

The skin skeleton

The interior space

Geotube is a proposal from Berkeley-based Faulders Studio for Dubai (natch) that self-generates a salt-based skin with seawater.  The building’s skin is entirely grown and is in continual formation rather than fully completed.  The building sucks up water from the Persian Gulf through a 4.62 km underground pipeline, and then sprays it over its mesh facade. The water will evaporate in the hot Dubai sun, leaving behind crystallized salt deposits, transforming the tower’s appearance from transparent to a highly visible white solid plane. The building will be used as a specialized habitat for wildlife that thrives in this environment.
