I bought my house before I was married, I was about 30 (53 now). I bought it because it had a detached barn, with horse stalls and all. It looked big at the time, 24 x 32 with 10' ceilings. The walls and ceiling are paneled with 1920s beadboard. I had insulation blown in, a 100 amp subpanel brought out from the house, propane heat and a big window AC unit, it is nice to work in there. I have been in the custom furniture making business in there for over 20 years. It is pretty tight now, with big machines for a 1 man shop. 24" 7.5hp thickness planer, 12" 5hp jointer, 5 hp shaper, 9 hp sliding table saw, 20" bandsaw, all 3ph with ph converters, etc, etc, etc, and on and on. The basement of my house is storage for lumber and veneer, again a lot for a 1 man shop, probably 5000' of solid and 20,000' of veneer. I have a 4x8 vacuum press down there as well, for veneer jobs.
About 10 years ago I built another detached garage (I am on 2.5 acres, neighbors are no problem), for a convertable. The car is gone, so last year I brought out another 100 amp sub panel, this year I hired 2 guys to insulate the 2 stories and put up 1/2" plywood on all the walls. Put in a top of the line Rannai propane heater as well. This has become the machine shop. Bridgeport mill, 13" SB lathe, 9" SB lathe, Wells band saw. Many tool boxes and this is only the beginning I have feeling.
The wife complains once in a while, but not much really. I am in business, and the government allows a business to write off tools and machinery. I take advantage of that in a big way. I spend it on tools so I don't have to pay taxes, works out well if you ask me!
I would love more space, but I can't imagine moving all this stuff. I will die in this house, someone else will have to move it.
