Located in Cambridge, Massachusetts... this 5,300 sq-ft home is rated as super efficient and made totally of plastic.
Why plastic? Well, the translucent panels that coat the exterior actually make the house extremely energy efficient. They're filled with insulation that locks in warm air in the winter and allows cool air to circulate in the summer. The roof is also colored light grey, so sunlight reflects off of it. And that all means that the bills are lower and the environment is happier.
