Earth Measure is the result of a collaboration between Minnesota-based stone fabricator Coldspring and Jason F. McLennan, Assoc. AIA, founder of the International Living Future Institute’s Living Building Challenge green building certification program. The stone line is manufactured chemical free from stone byproducts that would otherwise be ground up as aggregate or discarded as waste. Earth Measure comes in three patterns, whose inspirations include dried mud forms, the Fibonacci series, and linear strips, the last of which is intended for use alongside wood. coldspringusa.com
