Thanks Guys, I've got lots to think about.
Stupid thing about the windows is I replaced 5 on the house last year as the sills were rotting and they were kind of drafty. I could have just taken them apart and had 10 free windows for the shed.
I'd go bigger but I can't make it fit. The lot the house is on is the side of a hill that rises like 40', theres a plateau where my house is, and valley above my small back yard and the rest is steep woods.
I'm not planning to really do any work in the shed and the house has a garage underneath so the lawn mower and snow blower are staying in the garage. I'm really just looking to paint & epoxy there if I can get it warm enough. My folks used to have a tiny potbelly stove that heated our kitchen, I was thinking I could do the same thing out there as I've got all these trees for free wood. Sounds like I'll have to rethink that.
just so you can get an idea what i'm were this thing is going... Its taken me 2 weeks to get this cleaned out, leveled and the retaining wall built.. And the clocks ticking, I gotta start fishing in 2weeks. Ugh!
