Think that you could cut it living in a 20-foot shipping container? How about in a 186-square-foot mobile box, or perhaps even smaller, in a 43-square-foot single room? While these spaces may seem like a tight squeeze for the average American—who lives in a 2,600-square-foot home—tiny houses have taken country by storm in recent years. 

The freedom and simplicity tiny homes offer has captured the imaginations of many Americans. The biggest draw may be the mortgage-free lifestyle, but the consumer trend also represents much more than living without debt. As tiny home builder Ryan Mitchell says in an interview with BUILDER’s Jenn Goodman, there is a philosophy around the tiny house movement which focuses on connecting with the environment, simplified living, optimizing space, and, often, going "off the grid." 

Here, we've rounded up some of the best tiny homes featured on BUILDER, as well as sister sites EcoBuilding Pulse, Custom Home, and Residential Architect that showcase innovative layout designs, sustainable technology, and useful storage features. 

From larger tiny homes--such as the 425-square-foot laneway infill house in Vancouver, British Columbia--to a 10-foot-by-11-foot tree house in Scotland, these designs and articles will have you questioning the limits of square footage.
