Our new house doesn't have a backdoor

Well our new house doesn't have a backdoor which I find very odd. The other floor plan has backdoors and even a small patio but since we didn't get to pick here we are without. I hadn't thought much about it until tonight when I was preventing Grace from running away out the front door or the garage door that I was actually quite thankful that there wasn't yet another door I had to prevent her from escaping through.
