Happy holidays from the Open Building Institute's Seed Eco-Home. This is what the finished product looks like after much hard work. This is our showcase model, and we will open it up for public tours next year.

3.5 cords of wood - which is expected to last the winter season - is a lot of trees. This makes us think how the greenhouse and solar energy could take us down to zero firewood - outside of extreme weather days.

      WHERE are you located? Are you really going to open it to the public? How about a big Kickstarter backer party... with virtual participation for anyone too far away....

      Wow, this is impressive. Excited to see how things progress from here.

      Thanks for the lovely update and photos. Looking forward to the manuals.

      Jonathan: that is indeed much bigger—1500 sq of interior space. Since the foundation and roof are the most expensive parts of a house we figured we'd try to make the most of them by adding a 1/2 story (another 700 sq ft). However, for the next prototype we may go smaller just so we can nail the details (and increase build speed) before going bigger again. Of course we're willing to tell you about the cost of materials :) It took so much longer than expected and we ended up wasting some materials on experiments that didn't work, so it's hard to give you a very accurate number—but my estimate is $35k for the house + $15k for the greenhouse (in materials). Before the next prototype I'll make sure to do a more accurate calculation of what actually went into the house and then add 10 to 15% for mistakes and waste. In reality there wasn't much waste as I re-used almost all scraps and spare parts on interior finishing, the firewood shed, built-in storage, etc.—Catarina

      That looks a bunch bigger than the 700sqft seed. How large is it, and are you willing to let us know roughly the material costs?

      Francis: thank you, so glad you like it! Our next steps are to finish the prototype (there is still more to do in terms of wrapping up and calibrating the utilities) and the design/build manuals (the kickstarter reward books). Once those two things are done we hope to be in a good position to guide others in building their own versions. Happy holidays! —Catarina

      Absolutely beautiful !!! My wife and I would love to build this home. Please let me know when we can begin.
      Thank you.

      Dave Preece: Yes! We still have work to do on the prototype, but it has a reached a sufficient stage of completion to allow us to make the books and other rewards the main focus from now on. I need to do some prep work over the next couple weeks and will begin adding to the book on January 8. —Catarina

      So the prototype Seed eco-home is complete. Does this mean we can now expect delivery of Kickstarter rewards?
