I am not a tiny house dweller at the moment, and I doubt that I will have a house of my own for several years. Instead I will rent and have roommates, or possibly I'll buy houses with partners and fix them up for slow flips.
With that said, I am extremely intrigued by smaller/greener homes. I've spent a lot of time researching shipping container homes and other innovations like that. The TV show "Living on the Edge", which has two episodes, was right up my alley.
Since then I have been making sketches in my notebook of various home designs, but my absolute lack of architectural skills (not to mention drawing abilities) is a problem. Perhaps someday I'll consult with an architect. Until then I think the most important thing is to focus on what I need in a house.
Perhaps that's a good starting point for the rest of us. Make a list of what you need in a house, and go from there. My list is something like:
Room to work out
A smallish kitchen
A living/dining room to entertain
A bedroom with space for bookshelves, a desk, and guitar stuff
etc
I'm very much intrigued by the idea of having a bunch of windows to overlook an awesome view or something, and I figure I can balance out the poor R values by having a small house and insulating the fuck out of other walls.
If you're interested in badassing it in a shipping container, just google it up and check out images and videos on youtube. I think it's a great idea, and in fact I think it might be possible, if difficult, to literally ship your home to another area if you want to move!
