This Little Piggy's House is made out of 275 pound corrugated recycled cardboard that is itself 100% recyclable. The design team of architects, graphic designers and digital artists turned out an incredibly elaborate playhouse that features a window, two doors, a dormer, chimney, planter box and mailbox. While the unpainted house's $59.99 price tag may seem a little steep for cardboard, we think that the details and durability could justify the cost. Choose from a blank house in brown kraft or white, a house covered in hand-painted butterflies or a hand-painted house with a toyland motif. The California based company donates 5% of their profits to end childhood hunger.
