I am building a 10 ft x 12 ft SkyShed. Hindsight being 20/20 I should have gone with the plywood flooring. The 1 x 10'make a nice rustic floor, but you need to make sure your lumber is not warped/ crowns to make the flooring work. Also 1 x 10's are more like 1 x 9.25, so there is a discrepancy in the plans vs what you actually need for the building materials. I also modified to do T111 siding to fit with the architecture of the house. I am starting the roofing, and as a 1 person job....get two able body folks!!
The point about the warping/crowning on the 1"x10" lumber is a good one. The plans calls for a 1"x10" actual, as opposed to 1"x10" nominal. Nominals are slightly smaller than the given dimensions, which is what causes the discrepancy. "Actual" are the actual size given, but finding them seems to getting harder and harder.
I will have two able bodied people when I do the roof at least.
BTW, did you just do T111 over the studs? I was planning on doing OSB over the studs, wrapping that, and then putting the siding over top of that, but I'm wondering if the OSB might be overkill.
You have a nice looking spot for an observatory!
