This neat little home featured in the New York Times is Swiss inspired architecture located in the midst of a very traditional Polish town. The interior features simple concrete floors and particleboard walls. 

The exterior features prominent vertical planks of spruce, instead of the plaster exterior used in most of Poland's "castle" homes. While the planks are more expensive upfront than plaster, the planks will age better than plaster over time and save money in the long run.

Check out the photos below. I know it's not for everyone, but it is cool nonetheless.
