I think I may have found this very thing from Kids Crooked House.
These offbeat mini abodes are made by two cool Maine dads with a love of graphic design and a belief that kids should turn off the damn TV already and go play. The playhouses look cool as they are, in bright colors or more rustic natural finishes, but the team loves custom orders and can easily turn your kids’ playouse into a castle, army barracks, or wacky train station.
At these prices the playhouses are more likely to be found at school playgrounds or the play space of your favorite family restaurant than in your neighbor’s backyard. But hey, a mom has to dream. –Liz
