A couple of weeks ago, materialicious covered Kathy Tafel's KTainer project:
With partners, I own land in a remote part of California. It has wild beauty, and some need of environmental restoration. Our first years there were spent in basic infrastructure such as water and road. To be there on a more regular basis, though, we needed to not spend hours setting up and tearing down a tent each time we visited. My partners built a yurt. I am building a house framed by shipping containers.
According to her website, the KTainer house was made from 4 24' containers which she purchased on Craigslist.
Also on the site, she details the process throughout various stages of construction and shares pictures:
there is far more romance in the idea of a shipping container home than the actuality of building one. Working with metal is a pain. You need to know metal-working skills or someone who has them. It is dangerous to work with power tools of course, but angle grinders and welders are especially not for the faint of heart. I am of course happy with the result, but this has been harder work than I imagined, and I didn't do the hardest labor.
If you are interested in shipping container homes, or considering building one yourself, Kathy's site is a must-visit.
