The Green Dollhouse Project wants to engage people in some "serious fun" by designing, building and submitting dollhouses that are not only fun to play with, but healthier and more eco-friendly. The competition encourages designers to incorporate energy efficiency, water conservation, non-toxic materials and other green design practices into their miniature homes, but not at the expense of creating a Dishy Doll Dwelling: Your entry must, first and foremost, be successful as a dollhouse. It should delight children (and adults!) and hold up to active play. Creativity, inventiveness, playfulness, and functionality as a dollhouse are key features.
Good design combined with green design? Maybe next year they'll call it the Viridian Dollhouse.
We bought our daughter a dollhouse made by Plan a while back. It's made from rubber tree wood. It seems they used to just burn the rubber trees that no longer produced enough sap. Now they make them into lumber. To get an idea of what they look like - http://www.pufferbellytoys.com/pbt/Home/Page/Product_Detail/Item/2203
This is so cool. Makes me wish I had a daughter to build one for!
