I like to refer back to the bathroom shower builders who build shower floors out of cement and then add tile and also  build and add tile to the walls of the showers.  Of course we want those structures to last and not degrade due to water.   So the Tile installers and Shower Floor builders use  an Acryllic Admixture in their mortar and cement used to build the shower floor and when gluing the tiles to the floor and wall.   So why dont we build bridges and skyscrapers the same way....   basically they are making the concrete more waterproof and maybe stronger as well.   Well guess what,  Todays exterior paint is acryllic and I found some guys mixing cheap mis tinted store bought paint and mixed it with portland cement and sand  to make water proof concrete and also when thinned enough to be used as a water proof coating/covering much like a coating on roof shingles to extend the lives of shingles and protect the shingles
I am just now finding out ( I started another thread recently here )  about clay being used in concrete to make it last much longer as was the case with the Amish and when they built the Hoover Dam etc.

There are now many dozens of  ADMIXTURES  featuring many substances that make the concrete stronger,  impermeable so as to prevent the rusting of rebar reinforcement and concrete used for water tanks etc.    This new info needs to be woven into the science we already know about the many forms of concrete.  Expecially bridge construction is looking hard at the new sciences to increase the life span of bridges and skyscrapers etc.

For a few years I have been collecting data about fibers in cement, various admixtures  and how the Romans created such long lasting concrete.   Here is some info about how the Hoover dam was constructed and for old Amish  builders etc.    Check this out and  try to incorporate with all the other new info.

Go to the places that sell fish in aquariums and ask  them to keep the duck weed that they scoop out of their aquariums and sell to you .... duck weed is rapidly growing and cleans the water like many other plants but it is uniquely nutritious for ducks ( and humans as proven in china ) if you can develop an ecosystem that has plants to clean the water of duck waste and also serves as food source..... that is the goal.   Also water lillies etc.  When at the fish store also inquire about minnows that do not grow large but multiply rapidly.... they also clean the plants which put oxygen into the water.

The key to affordability is HIGH DENSITY .    This is proven for us in very hi density population countries.

I'd say the Holiday Inn or any of other dozens of hotels offering rooms with sm kitchens and bathrooms etc.
to provide some templates.   I have heard of hotels being converted into privately owned condominiums

A good idea would be a  look at Korea and Japan  at the multi story sky scrapers with smallish apartments for families to live in.    This is also the same way we solve the problem with growing numbers of homeless people.

I own six residental rental properties  and over 25 years I have settled on  a tile called CVT  Composite Vinyl Tile  which is used in hospitals, stores and airports etc.   It does not look as good as the new vinyl planks that resemble wood  but the CVTs have color all the way through if they get scratched etc.   The Vinyl Planks have the wood look painted on the top of them and it scratches right off.   There are many CVT colors to choose from.  # 1 they almost cannot be damaged but if one was damaged, pull the tile up and replace it in a small amount of time.   In bedrooms I now depend exclusively on Carpet Tiles.  The hi quality ones are also used in offices and airports and stores.   Once again,  if one is damaged or dirty or anything, pull it up and replace with another.
Kitchens and Bathrooms get the CVT.    I am not looking for the elegance of hard wood floors in rental properties but the look is entirely acceptable.... think about the banks and stores and offices that you have visited.    All floors are pleasing enough to not make you notice that it is super versatile and rugged.

This is a great video that addresses many of the issues in this thread

This is an exellent and thorough video explaining the different stone wall techniques for the last 20 centuries

There is lots of useful and important information in the past issues that are available  like  "Understanding Integral Waterproofing"  Spring 2010
"The Basics of Integral Crystalline  Waterproofing"  Spring 2008

It is too bad that this company did not make it  because their finished product is truely a masterpiece worth owning.   The collapse of the company had to do with the expense and overhead of setting up and training franchise operations.   I live in Marietta, GA a suburb of Atlanta and the first attempt at
setting up a marketing/installation  operation including a full size demo house which was used as their office is about a mile from where I live.
Today,  the house on the lot sits vacant and abandoned but it is easily inspected and viewed.     I'd say the lot is zoned commercial  and thus best used as office space instead of residential space.     I' think the reason for coorporate failure  was because .... probably like a lot of other dome designs..... was because of inability to obtain loans for placement in normal neighborhoods because of space ship appearance.   If you own your own land in rural areas then maybe not a problem  but still a bank might question the residual value if borrowers cant make the payments.   Most of us arent ready to pay full cash up front for a major project like this.   The company was way ahead of their time and with really big bucks i believe an entire subdivision could be designed and built using these structures  which would eliminate the  "odd duck" syndrome with  placement of spaceship houses dropped into conventional structure developments.
