Green is definitely the new black and even doll houses can be eco-friendly and sustainable. This model called, The Modularean Eco House was designed by an architect by the name of David Baker and built by Julianna Sassaman. There is no info on the materials used but it looks like wood played a big role in the design of this make-believe house and I can see what looks like a solar panel on the roof. Any way, this doll house is so much cuter than the doll houses I used to play with up until last week. Just kidding.
