These are the plans (see note in red below) for the new larger ihouse 2.0. I like that they've added more overhang to the roof, but don't think they should have stuck with a butterfly roof design. It's bad enough getting leaves and blown dirt out of gutters but to have a large roof configured in a shape that collects them...
2017 note: The i-house was in production for only a few years, and any plans for a doublewide i-house 2.0 are long dead.) Don't despair! With Warren Buffet's money, Clayton will come out with exciting things, just as they did with this 2015 AMIE 3D-printed carbon fiber prototype house in cooperation with Oak Ridge National Laboratory and others.
Here's Preston Koerner's take on the plans for the new ihouse, from JETSON GREEN.
I'll have more to add to this post when I look at them more carefully. It certainly doesn't look like it is going to be cheap, but the people clamoring for a larger house should be happy.
Here's the offical ihouse 2.0 plan form, where you can write about all you like and don't like about the house plans. (Frankly, this is what they should have done for the first incarnation! It's a very good idea.)
