Ron, we've never seen a patio kit for a little ramp like is on a side entrance. Is there a screen included in your side entrance? Maybe a pull-down located above the ramp?
I don't see a problem with the ramp handling the weight of two people on the ramp drinking coffee or whatever, but you don't have room for four people and chairs in a 4 1/2 by 8' area so why worry. At motorcycle rallies we usually see people with the rear ramp down being supported by 2 long home-made saw horses. I believe you will have to use your inherited ingenuity to devise the fence.
