Everything about this is ridiculously cool! Except the whole having to live in Texas part.
Over the course of my 61+ years, I've lived in Missouri, Colorado, Utah, Ireland, Scotland, Alaska, and Texas (some of those more than once). One of the things I discovered early on, is that you're about as happy as you decide you're going to be, no matter where you are. I've managed to find beauty in every place I've ever been, even the North Slope of Alaska in winter, and west Texas.
I'm self-employed, and with a few conditions, I could live anywhere I want. We actually own some nice land in the mountains in Santa Fe County, New Mexico that we were going to build/live on (I like the climate there a lot better), but there is a huge difference between building there and building here. In Santa Fe County, the zoning laws are unbelievable! They tell you how tall you can build, where you can or can't put it on a hill, how much you can use your own water well, etc. The list goes on and on - the zoning regs are many pages long. By contrast, rural counties in Texas have no, as in zero zoning laws or building permits. The only single permit I had to have for this whole place was for my septic system, and that took a 10-minute inspection of the soil. So that is a big part of our decision to stay here; less over-reaching government on every level from the county and state. I could list many other reasons: no state income tax, business-friendly environment, 2nd Amendment-friendly, natural beauty, water rights, etc. Bottom line is that Texas has been very very good to us, and we love it here. YMMV.
I can’t wait to build my shop and house. I don’t remember seeing the dimensions of your shop (including the guest suite).
My shop building is 75'x30', including the guest suite that we're living in now. I designed the actual shop space to be the same as my last shop, which had adequate space for my needs. Larger is always nicer, but there is a balance between space and cost of course.
My plan is for a 50x70 building with a guest suite in it. We will live in it while I build the house.
Good plan; I hope you enjoy it as much as we do.
Thanks!
