I don't fully understand what you are asking. What I visualize is you have a landing then one more step then the door opens at the edge of that step, is that correct? If so that would be awkward in your transition if not dangerous, especially going down the steps, you would open the door then have one step down immediately. For someone not use to that might fall, especially an older person.
