this makes my point about using recycled materials for amazing things. inspiration: cardboard favela (Brazilian slum dwellings) now this is pretty cool and I may use this idea as inspiration for a canal I want to build later on :)
Up House from recycled cardboard boxes, even my cat wants it for itself! Just create the structure with cardboard, add some glue and toilet paper, add the colors, add all the details and voilà. a fantastic Up house!
