AAC block construction

Information shamelessly lifted from the Rittersburg Castle website.

AAC block looks similar to standard cement blocks (in material) but has slightly different shapes. It appears to be something that an owner builder could use. Looking around on the internet and checking various cement block or other construction methods (such as ICF), the cost per square foot of wall doesn't seem to vary more than a few dollars ($9-$13/sq.ft.). Multiply a few dollars by a few thousand square feet though and it adds up. I think some of the variables are dependent on how much you do yourself, the quantity of material ordered, where your nearest supplier is and the experience level of your work force.
