An interesting articles in the Huffington Post by Claudia Canavan takes a general look at tiny homes and micro living in the UK with an emphasis on the eco element of it. Here's a snippet:

Plus, tiny houses lend themselves to more intentional living, as you can’t go mad in the sales and just stick any guilty excess under the bed.Mentions for, and chats with, Tiny Eco Homes UK and Tiny House Cabins (pictured above). Well worth a read.
