I use the title as a joke, but in fact that is the basic start of the walls of our new home. The truth is that the house we will build is made with insulating concrete forms (ICF). You can see more about it here and here. The outer walls will be forms that have channels which are filled with concrete and reinforcing bars. The building cost is 2-4% higher than building with wood.
The savings come later as the home will be very energy efficient, safer in extreme weather, and has a very high fire rating. The home needs 44% less energy to heat and 25% less energy to cool. This was a contributing factor in our decision to build this type of home.
I am certain we will attract a large amount of attention when we start building. It will be exciting to watch the house come together with such unusual building materials.
