As highlighted recently at Dwell, Tiny House Swoon catalogs homes with a light footprint, from rustic to modern and everything in between. You will, indeed, swoon.
The Tiny House Blog features workshops, an international directory of tiny homes, a gallery, and plenty of interesting tidbits, like this one: The average home in Costa Rica is only 400-600 square feet (the average American home square footage measures around 2,400, though experts predict this will drop to about 2,100 by 2015). Proprieter Kent Griswold also maintains a great Pinterest page devoted to tiny houses.
This Tumblr tends to focus on the mobile and the rustic; what's not to love about life on wheels? You'll also find practical curation, such as this post detailing smart storage solutions in small spaces.
