I'm actually building a tiny house right now. There are actually workshops about building tiny houses put on by many of the professional companies that build them. I used to work in construction so I came up with my own plans and am doing it all based on what I already know. I'm currently working on a blog/website about it, so I can add the link in the very near future if you're interested.
As for my hobbies, I'm interested in building things(see above), music, as well as cooking, canning, and reading. Last year I set myself a goal of reading 52 books and actually surpassed it, making it to 60. Of course, this year I'm working on building my tiny house and will be attending grad school in the fall, so I don't anticipate getting anywhere close to that number in 2014.
