Pinterest does it again. This site never ceases to amaze. Pinterest is so good that I have to be careful not to spend too much time there or other things won’t get done. They seem to have endless high quality images of every imaginable topic, although as mentioned previously there’s no convenient way to search their site, so I use my favorite search engine.
Earth Houses + Name of Country
Looking at photos of natural houses is a fun way to learn about natural building. Almost half the homes in the world are made with earth (adobe, cob, rammed earth, earthbag, etc.), so there are countless photos of houses made like this on the Internet. Try searching for photos in your favorite search engine using the search terms: earth houses + the name of country you are interested in. Google Images is my current favorite (although the quality is slipping lately). Try various search terms to see what works best. You could try searching: earth dome or earth dome home or earth roundhouse or earth sheltered house. You get the idea. In foreign countries you could search similar words in the local language.
