ZERH to Begin Construction

The final adjustments are being made to the plans for the first ZERH home in South Central Kansas, and probably the first ZERH in Kansas.  If anyone is aware of a ZERH in the metro KC area of Kansas, I would appreciate a comment.This home will be built in Derby, KS. a Wichita suburb.
