[GSBN] Prefab straw bale systems for TLS

[jfstraube]

A very wise comment by Lance, IMHO.
Labor costs, competitive material costs, and competitive wall system costs all vary widely in my experience.
In the US and Canada, there are projects where $400/sf (!) of wall area are budgeted, and others were it is tough to get $20.  Labor rates vary from under $20 to over $60/hr and productivity may vary by a factor of two.
The construction costs in central Stuggart are much much more than downtown Kansas City (real examples for me), and the costs of housing in San Francisco/Boston infill has almost nothing to do with suburban New Mexico.
