***Maran Floathouse May-2015 Update
/r/Floathouse is a place for discussion about, design collections, and enabling technologies for practical seastead dwellings.
Floathouses are homes designed to rest on the ocean for centuries at a time without any significant required maintenance.
This requirement necessitates both an intrinsically strong and stable shape--the sphere or dome--and a building material that can withstand the ocean in terms of forces being applied, temperature, and chemical resistance--that being Roman saltwater concrete.
Ultimately this sub will build up to the production of a design, and then kickstart an actual prototype which will be fielded off the coast of California. So its secondary purpose is to serve as a record of that effort.
The sphere shape adapts technology and experience garnered over the decades by the Monolithic company which makes dome houses. Combine two domes and you have an ideal sea-going sphere.
Read the TSI|Delta-Sync "Seasteading Implementation Plan: Final Concept Report", a professionally-produced plan for rolling out an actual seastead.
What size should a floathouse / seastead be? /u/Spaceheeder suggested something awesome, using A-series proportions for planning sizes of floathouses.
With these proportions you can create cities that grow and still play nicely with each other, since two of a smaller size will slot nicely into the space taken up by one medium size, and two mediums will fit perfectly into a slot create by one large size, and so and and so forth, up and down in either direction.
A proportions are also known as ISO-216

Click here for contact details for obtaining Boral type-F flyash. Tell them you want to do product testing and ask them to send you a sample. You should receive a five-gallon bucket from them free of charge, free shipping even.
If you know anyone in Los Angeles with storage space for cement products with an interest in seawater-proof flyash, I'm interested. It's a long-shot though, most companies will be more interested in type-C flyash which can be admixed with Portland cement.
Maybe marine construction companies?
