Another ICF home goes out of our office this time for Mike Tervoort Custon Homes this will be Mike's first ICF home. This home will be built in the Zeeland area and will be using many other green building products. Mike is using the BuildBlock ICF wall system. This is the first time I have specified this ICF block and am lookig forward to his feed back on it. The block is distributed by Wall Tech Product out of Harbor Springs, Mi.
