From before...
The driveway goes from the front of the street, beside the house to the back yard. Originally I wanted a front and rear exit, but the gradient to the alley was to steep. I could have gone with just an alley entrance, but then the driveway is a bit wasted, and the alley is fairly tight, steep, and super crappy in the winter. I'm happy I went this direction with it, as I don't have to worry about the door facing the alley being left open or broken into.
For heat I've actually got a 10ish year old house furnace I got for free, so I'm going to put that in.
