So, what started as a shed project turned into a "well, while I'm pouring concrete, I might as well pour some for a garage addition as well" type of situation. Here are pictures of the Garage pre-modification, and some shots during the concrete phase.
I contacted my local building codes, found out just how big I could build according to local code. Between the new shed, and garage addition, I will be slightly under the allowed limits. My main reason for the garage addition is because I have a heated area (the stall and a half on the right side) which was just not big enough for my tinkering needs. I wanted a bigger shop.
My land is very sandy so I had a good base......but that wasnt good enough for me. The new slab was to be poured above grade somewhat, so I was a little conserned about the far end of the slab sinking over time. So just in case, I got a 20" auger on a skid steer and sunk 4 18" sonotubes 5' down as some support pilliars. It will not sink anymore.
The new slab was poured 2.5' lower than the existing slab. It worked out well for me because of the natrual slope of the land, and the roof lined up just right. I have 10 foot ceilings in the current garage. I was looking for the magic height of 12'6" for the future hoist.
