The next time you find yourself crammed in the a middle seat in coach, drinking a tiny bottle of wine in hopes of catching even a few moments of sleep, drift off to images of the life you might have lived: aboard a private Boeing 747-8. These luxury planes are bigger than many of the houses featured on this blog, with 4,786 square feet (444 square meters) of cabin space. The plan in this post was built by Boeing, then finished by Kirkland, Washington-based company Greenpoint Technologies. The final results are nothing to sneeze at with luxury lounges, private bedrooms, and even a full formal dining room. It's no wonder that the U.S. government has said it will buy 747-8s to be the next Air Force One.
