Muleman, you have some good thoughts there. Thanks for your post!
I haven't heard too many people talk about multiple buildings when talking about tiny homes but that would make a lot more sense than building a 200 sq ft tiny home and forcing it to be everything a person thought they needed for a homestead.
Living in an rv parked beside my parents' place this summer, we made pretty good use of a pavilion right next to the rv. It was nothing fancy but was a roof over us with two picnic tables set up end to end where we did a LOT of work. That's where we shelled beans. That's where we processed our corn. That's where we processed our carrots and red beets. That's where a lot of "family time" happened while doing those things and many more. I set up a 60,000 btu propane burner out there for things like blanching corn and cooking red beets. It worked! And it got me to thinking seriously that an outdoor kitchen would absolutely be a wonderful thing to have on a homestead. It could perhaps serve more than one function if large enough. It could be screened or even walled in if desired. Lots and lots of possibilities.
That said, I'd still want a decent kitchen inside the home. There is winter time and the adjoining seasons when heat in the house is a good thing most places. It's good to have room to bake bread, holiday treats, and cook sizable meals for family get togethers. Plus, the kitchen is the hub of a country homestead anyway, isn't it??
My wife and I go through the discussion fairly often... I say, why not just a nice small 2br for the two of us. She says, why not a 4 or 5 br for when family comes to visit so they'll have someplace to stay. I like having the big kitchen and a comfortable place to spend some time. But I've even tossed out the idea of having small "cabins" on the property that could serve as "guest rooms", perhaps resembling "tiny homes". We'll see what comes of it.
