Thank you guys!
I think a floating solution could be the ideal "platform" to make a very cool collaborative city - group project, without the constrains of snap-fit downloadable plots of land. What do you think?
I'll begin explaining some concepts using just one main structure:
This we call "Ramform Island", it's basically a large, light cement ship with a broad moonpool. It is just one possible solution for surface, sun-drenched, platforms.
Initial Floating Harbor,it begins with a tall bow, a clear point of reference.
Initially the moon pool space might be used as a marina. while the inside of the breakwater could function as terraced condos
The lateral breakwaters (joined at the wave-splitting bow) can grow, in segments if necessary (sea train) and make the surface area of the protected moonpool exponentially bigger
Allowing bigger ships and a floating village of smaller, lighter, individually scaled sea houses to cluster inside.
Light truss floating houses can provide outdoor and semi outdoor space in a smaller, less dense scale than the large breakwater condominiums.
Just as well the whole thing can be part (or travel among) larger clusters of different marine cities (in reply to your question @BillM )
