Building Castles

On many beaches throughout the world there are competitions for artists to sculpt the most well thought out and structurally sound sculptures out of sand.  The only materials are sand and water and the perfect balance of the 2.  In competitions I have seen the final product is then blown to pieces after being judged.  It is something that has taken the simple sand castle to an artistic extreme.  But something I have started to learn something about, called rammed earth is something that is so similar and much more permanent.  Rammed Earth Homes are not only healthy for dwellers and provide an beautiful alternative form of the most basic idea of shelter, but they are a green form of building.
