Might take some ideas from the contrsutcion of these as well. But I think geodesic domes with modular panels is probably the way to go for any structure that doesn't actually require a different shape. It's got about the best track record for high winds, and encloses more space with the least amount of materials. damaged panels can be replaced without affecting the structure.

I have a soft spot for geodesic, and especially tensegrity, structures as well.  They are structurally superior to the typical rectilinear sheople shack, which tends to fall down in earthqakes and gets blown down in hurricanes. http://www.domespace.com/fr/accueil has some very nice looking, but not geodesic, domes.  The monlithic cement dome also has a proven track record surviving hurricanes and even a tornado. For fiber reinforced concrete, I can see casting something like Roger Dean's (designer of Yess album covers) very organic home designs, http://www.rogerdean.com/architecture/index.htm ,  http://www.rogerdean.com/architecture/willowater.htm . http://www.geocities.com/flyingconcrete/index.htm also has some designs which can be adapted to casting.

I surveyed a lot of different prefab designs a few years back to quickly build worker housing on a beach front property near the planned Trujillo, Honduras construction site for the Freedom Ship. The Topsider came up in a search for "pylon house", and was an ideal candidate since it was available for export from the US as a complete kit, simplifying the task of trying to find building materials locally in a developing country.  Converted shipping containers and a stackable design which ships as a shipping container were also strong candidates for a high density housing project, http://www.fabprefab.com/fabfiles/containerbayhome.htm . Shipping containers can be stacked up to three high.

I had also considered converted shipping containers for sea colonies which would be live-board ships which would circle the oceans importing materials and components, processing and manufacturing enroute, and exporting along the route. The modular shipping container housing would allow residents to easily move among ships and land based colonies, like the dynamic geography of Seastead. I came across Freedom Ship while researching the idea and joined the project since it was along a similar line of thought, though not modular and flexible.

http://www.fabprefab.com/fabfiles/fablisthome.htm also is a list of some very nice prefabs with modern design.

I love this, great find!

I suspect we will be able to learn a lot from the techniques they have develloped. Lightweight, sea-storm-proof, and designed around the same unconventional foundation. You could basically place these on top of a spar and be ready to go.

Another advantage is that they can be moved the same way they are delivered, making the infrastructure easier to detach from the structure.
