The news has been reverberating throughout the green building and design community since yesterday, but it still hit me like a sledgehammer when I found out this morning. Michelle Kaufmann, known as the queen of green prefab architecture, has been forced to close up shop due to the crappy state of the economy. I have featured her work before — her mkPURE sink is made of concrete and recycled porcelain. What I never wrote about, much to my regret, is her beautiful green, pre-fab homes. My husband I spent a lot of time at her firm’s website going through the floor plans and planning our life in one of her homes. I’m not kidding. We had it picked out and were just waiting for our financial situation to catch up to our dreams.
