I set the footings yesterday and today, with some help, got the flooring, walls and roof up. I was happy just to get that done, it should be the hardest part of the whole project.
I have not secured the roof to the walls yet, so it is essentially sitting on top of the walls, but those are renforced and have extra supports (those funny looking 2x4s that are set at angles). I hope a strong wind doesn't come along tonight.
Tomorrow I plan on shoring up the walls and covering the roof with roofing felt and shingles. Good thing the Skins game is on at 4, I have a busy day ahead of me.
