Good Job ! 37 years ago my wife and I built our house in 2 1/2 years , it was the ONLY way we could afford a home.
Excavation , Concrete, framing, plumbing , electrical were all learned and applied by books and OJT. I farmed out the sheetrock and finish since we were expecting the birth of our first born , ( unplanned of course ! ). The only thing I had built before that was a tree house as a kid.
Are there things I would do differently today , damn right I would ! But I do thoroughly enjoy the fact that every issue in our house was caused my ME.
We didn't build a normal house, it is a superinsulated two story home framed with 2X12 's . The cost for the home , power, septic, water cistern was about
the same cost as a new 85 Corvette. Times have changed. Good to know there are other owner built homes out there !
