I found a rather interesting article on biomimicry. There are designs for a building that creates its own facade using the salt from sea water. You can see the full article here:
It’s Alive! Faulders Studio.
It doesn’t directly link to my concept for the city but I do like the idea of a future version of this. Possibly it could be incorporated into another countries city design.
It is definitely something to keep in mind as possibly a secondary thought to how the city is constructed so quickly. Plus it does link with the idea of self-sufficiency as the city would be utilising the coastal location.
