. The Rion-Antirion bridge in Greece is built on floating pylons that have 70m diameter – they are of course concrete shell structures – so the size has already been done by somebody but it is pushing the limits of technology . If you check on the size of the drydock where the baseplate was built, the size of the “float out operation” etc… you get a picture what kind of cost (and budget) are involved to build just the first of your “modules”.
Rion-Antirion.

. The legs of Troll A have a diameter of 24m a wall thickness of 1m – still quite a enormous building job…

The picture below shows the building site of the platform baseplate when floated out from drydock. You can see the round molds of the start of the leg building in the center of the floating construction site. Your site would have a comparable size.

IF we float out something BIG like a city block –
What kind of structure (beside being a concrete shell) will it be? – Obviously it will be something that has been done before – nothing fancy in size, nothing fancy in shape, nothing that touches “never been done before engineering” ground.

So what has been done before in city block sized permanent floating concrete shell structures is the following:

A – round shell structures.

Here are some examples the pylon base of the akhasi bridge. A round (concrete cylinder) shape of city block size. Tanks in the oil and gas industry, cylinders, domes, and assamblies of cylinders and domes like the base of sleipner (right).

. . . . . .

Taking what has been done already and variate it “slightly” is a good approach that takes the “guesswork” out of seasteading – there is no doubt that you can build a couple of buildings on such a structure and “roll some grass over it”.


That kind of structures need a billion dollar oil and gas financial muscle behind to come to reality – and they are still “single pieces” not in dozends – so i don’t see it go farther than “computer graphics” at the moment.

What brings us back to basics – we probably have to do much smaller cookies and take it from there.

So family house or apartment sized concrete shell structures MIGHT be in reach – but it is still difficult to find an investor for building a 20m shell structure.

Honeycomb in Architecture

XawnfRTHrotqw1goc6APGH2do1_500.jpg . AAPJUNE1.jpg . AAPJUNE2.jpg . AAPJUNE3.jpg . .

Strong and light structures in compound curves. Land based and water based honeycomb structures (last picture the structure of the WHY yacht). It is obvious that honeycomb structure building will cook down to a similar price per squaremeter living space cost - no matter if it is performed on land in a building or at sea in a floating structure.
