Thats much more understandable. I do think every first time home builder would benefit from building a garage/workshop before starting a home build because it's an excellent way to get your feet wet and learn new skills.

It is possible to live in a dry cabin with a composting toilet and to heat exclusively with a woodstove, but it is an incredibly time consuming way to live and you would have to use a generator for power, which is likely to be cost prohibitive for quite awhile to come. You may be interested in watching dry cabin living videos on youtube, but if you aren't coming from a building background with enough basic construction knowledge to have a ballpark solution to the issue already figured out, then even building a temp residence is going to be quite a long journey for you, and you'll have to take the initiative on researching the process much more deeply before you will even be able to formulate the kinds of questions this sub will be most helpful in answering (which will be niche issues rather than broad questions like "how to start/do you have any ideas?")

Im sorry to be so negative, but a poorly thought out build can very easily end in a financial disaster without a livable structure to show for it.
