WikiHouse – Open source, modular, wood based, zero carbon housing
I think this is overly complicating the process. If you want an open source DIY method of building a home, just learn basic framing and construction. It's not hard, lots of people have built their own homes, you just need some common sense and a willingness to learn.<p>If you want to go all in on modular, wood based, zero carbon housing then learn how to build a timber frame house. If you really want zero carbon you can use only hand tools and harvest your own trees.<p>Wikihouse seems more for people who want to buy something off the shelf, pretty much a kit house. That's not a bad thing since it takes a lot of effort to build something as big as a house and lots of people don't want to do that. But I don't think this should be sold as a solution for DIYers since the existing methods already satisfy the listed requirements.
