That is really neat. I looked at some plans for something like that a year or so ago when my wife and I found a piece of property we were interested in buying. It was sold just mins. before we were going to make an offer and then back on the market for twice as much 10 days later.
We still may do something like that in the future so I can't wait to see more progress pics. BTW, pic 11 is very nice.
