Sorry for the post&run folks; didn't have a pic handy and the weekend was spent picking pumpkins and apples and taking hayrides with our toddler.
Here's a couple pics... The house is ~70 feet in from the road, so the road is ~30 behind where this pic was taken. The garage is 90 feet from the back corner of the house. And forgive the mess in front of the garage; i'm emptying the last of the crap out of it and spent today with a trencher digging 240' of French drain to (hopefully) solve the water problems in the basement of the main house.
Another pic from the back corner of the house:
Saving the flat roof is not an option, as it's completely rotted through, including what's left of the beams that support it (read: while tarping it last fall I fell through the roof a couple times). The block is good though, so worth salvaging as a garage/workshop.
I figure it's far enough back for a barn-look would be ok, but am open to suggestions.
