Amazon truly sells some amazing things, and while I order pretty much everything I need off the site — hey, you can't compete with one-day shipping! — this incredible DIY Backyard Guest House ($7,250) takes the cake. Parents who need to get the heck out of dodge for a few hours, or grandparents who live a too little far away, can sit back and relax in this 172-square-foot customizable house that you can actually assemble yourself in a mere eight hours. Keep in mind: if you want to add electricity or AC, that's on you to figure out! Scroll through to get a look at this beautiful little dwelling, and try not to envision it sitting right in your backyard.
