In the last couple of decades cardboard has been rediscovered as an architectural material for being light yet load-resistant, recyclable, nature-friendly and warm, just like wood, from which it is derived. Treatment with different chemical materials and production techniques allow for higher fire and moisture resistance, greater strength and flexibility: some of the buildings, made entirely or partly of cardboard, boost a life-expectancy of approximately 20 years. However, cardboard’s actual big time popularity can be observed in interior design, where creativity is mostly unlimited by structural and safety requirements. The recent environmental trend of recycling various objects has really led us out of the cardboard box through imaginative, witty and cheap designs.
