I have been interested in alternative methods of construction that use discarded materials of industry for home construction. Here are a few examples that I found interesting in reference to history as well as modern design.
First are the shacks constructed in the 1930’s in a makeshift shantytown known as Hooverville as a result of the great depression.
Another project that uses pallets to create shelter for the homeless. This is an interesting concept that would be affordable in the right climates depending on insulating substrates.
Here is an alternative of an affordable combination of materials called Papercrete. This is used throughout the country to create long lasting insulated structures or dwellings.
