Forgive me, Newer PlayStation player here who hasn't unlocked Creative Mode yet.

I'm working on my house on my friend's server. Can I:

1. make a custom wall blueprint,

2. before building it, place a basic wall blueprint against it,

3. build both and be able to attach a climbing rope to the basic wall to access the top floor?

Think of a two-storey custom house. On the second floor, you go out a door to a balcony of custom floor. Out here, against your custom wall is a basic wall with a rope to access the top of the second floor "roof" (but really another custom floor) instead of stairs to save space on the balcony. Is this possible?

And back down on the first storey, to access the second storey, what is the best way to achieve an L-shaped staircase? Do you know of any examples of how to do this, preferably with the much cleaner, narrow "Simple Stairs"?

I feel like the Simple Stairs are an odd height and that having two of them in an L-shape would be too tall to reach the second storey lol
