Like Entropy... Free isn't always the cheapest route Ryan and if it's not comfortable you'll never use it. I look at quansuts as an eye sore and of no significant increase to a properties value.
I think I have $45k in my 30 x 60.. probably cost you $55k these days to build.
8 course block foundation, 2 x 6 walls with 10 foot ceiling, 60 ' span truss roof (so snow doesn't come down in front of doors) 5 - 9 x 9 Garaga insulated doors (don't go any smaller than that!), 6 inch cement slab, R52 ceilng/ R20 walls, Galvinized ceiling.. drywall'd walls. 6kw heater barely works to keep it 52F all winter... small parlor stove from my Gramma's on Glamour Lake keeps it toasty with about 8 logs / full work day.
man.. it's been a long time since it looked that clean! lol
