Supporting turn in staircase after floor removal...

[Adam182]

Hi everyone, currently in the process of merging the toilet/bathoom together into a single room.

The toilet room was stepped down into the kitchen and I'm now looking to regain that headspace back by removing the old toilet floor and taking it back upto the new bathroom floor height.

The problem being it will leave the turn at the top of the staircase unsupported in one corner.

I've knocked together a rough plan but just wondered if anyone had any better ideas or reasons why this might not work.

Thanks any feedback is much appreciated.

The new dark brown vertical newel you've overlaid can hang the unsupported corner from the new joist above, if fixed to both?

That's what I was wondering, is supporting a joist below from above with a vertical piece a legitimate way of supporting? I was also wondering what would be the best method of fixing this way.
