there is an idea! maby 30x60 with the gable end facing forward?
The downside to this is it being on the hillside that's 60 of digging to clear out a level spot meaning a taller retaining wall! I'll try and get a pic of the location tonight so you guys can see it. I'm trying to squeeze the garge in between 2 huge boulders on a hillside close to the house haha. If I accomplishe my goal you would almost be able to step off of the one boulder onto the roof!
