We have a concrete front porch, a concrete pad between garage and shop and a concrete back porch. None of it is connected by sidewalk yet. We are going to do that. My issue is what to do at the front porch. Do I do some kind of concrete to the gravel circle drive in front? Do I connect it around to the garage? Do I use a different material?

For the back porch, I think we can just put in a sidewalk that goes by our hvac units and connect it? Maybe make it curve.

We are in zone 7 for plants, and any ideas there are welcome. Thanks!
