Where can I find hempcrete houses for sale?

A google search will show you the answer!
But right now there are not a lot of houses like this out there as the word hemp still carries a negative association with it. What I’m saying is your options are going to be limited for now.
As it becomes more socially acceptable there will be more and more houses for you to select from.
The big movement right now for Hempcrete houses is mini houses being made of Hempcrete. This might be the easiest way to locate or purchase a Hempcrete home.
