I've been out of internet connection for a couple of days, due to some technical mistake on my own part, and later on account of Independence Day, which gave my husband two days off work.

Now that I'm back, I've been watching some videos on sustainable and economical house-building, and I thought a couple of them might be interesting to you, for example here.
And here is another video... I especially liked this step-by-step tutorial.
