Old cardboard boxes should not be discarded easily, for it will definitely add up to the piles of landfills we have. However, the creation of artist Luise Valdes called the Cardboard House can be eco-friendly but definitely not an ideal place to stay. If you were to look at the pictures, the entire house looks awful if this will be a real place to leave. On the other hand, if you were to build house like this in a third world countries with various street people, this can be of big help especially during sunny days, but nor for rainy season. However, the artist’s idea of reusing old cardboards is perfect enough to show the world that we care.
