So here we go again... I decided to solve the stair problem with brute force. First of all I didn't want to spend the time building an elaborate stair that really won't be seen nor do I want it to be the focal point of the model (it's the insides that's the focal point). I also wanted to solve the "3-door problem" and this solution solves both.
It's not pretty, but it's very practical. I covers that third door and if we imagine there's one in there, it will be an inside access to the outside stair so you can go upstairs without going outside in the rain. It's also a private entrance to the apartment. I first design the enclosure to hide the supporting trusses, but then realized that these could be exposed and add more interest to an-otherwise funny-shaped box. I don't have to build any stairs are all since the door will be closed and the upstairs window won't show anything. So if this is in the back and not very visible, it won't matter since it's not much to look at, but it's realistic and is architecturally relevant to the era.
