18．In today's consumer world，we've never had so much，yet it seems we've never been so unsatisfied．The cost of housing has been rising for decades，and the cost to the planet has been huge，too．But there is a way to live a simpler，greener，and more affordable life：buy a TinyDwelling home!
TinyDwelling homes are very small，yet comfortable houses at affordable prices．Each TinyDwelling home has a contemporary design and included a living room，kitchen，bathroom，upstairs sleeping area，and convenient storage space．TinyDwelling homes are cheap to run and ecologically-friendly，too．All you need is a small heater to keep your house warm in cold weather，and solar panels （太陽能電池板） in order to provide light and electricity．
TinyDwelling is part of the small-living movement that began in the late 1990s．Back then，a growing number of people began to live in very small homes．They wanted to reduce their possessions，living space，and energy costs，so as to lead more ecologically-friendly lives．But the sall-living movement really took off after the economic crisis of 2008，when many people realized that they couldn't afford to keep large homes．
Lizzy Morriaon，a small-living enthusiast，started TinyDwelling homes in 2008to meet the needs of these people．Since then，Lizzy has been designing and building homes nonstop，and TnyDwelling homes have become so popular that thousands of people have bought one．And Lizzy hasn't only designing and building houses．She has also been teaching people how to build them．Simply buy the plans and materials so that you can build your own home，and save even more money!
