I thought that design was kind of interesting, though I see some problems with it, like: Roof pitch--I would think that in moss-prone areas you would have to consider metal roofing, because it would not be fun to get up there and spray or put moss-removal crystals at the top every year. Windows--they are set in so far back that I would think you would not get a whole lot of light in the house, even if you put large mirrors on the side walls. I'd hate to be running the lights all the time in the middle of the day. I don't know if the roof is too steeply pitched for Sun Tunnels or Solatubes. Overall, the design reminds me a bit of the Gravitron ride at the fair, or the Lost In Space flying saucer....hehe. Here's the link so you don't have to go back to the other thread: http://www.energy-efficient-house-plans.com/pyramodule-house-plans.html I hope the other site comes back up soon. Anyone have any opinions on the design itself?
