Removing pillar of a balcony

* Any other suggestions to make this work?

Yes, engage a qualified structural engineer to prepare a design.

I’m not being smart, but there’s a lot going on in your suggested system which you’ll inevitably miss as a non-structural engineer.

This is not a post that can be fully answered here. You are loading a building wall and its foundation, as well as providing uplift on the wall carrying the beam. Those details need evaluating and likely that cannot be done here. Hire a local structural engineer and be done with it. This cost of construction possibly requiring reinforcement of existing walls may well change your mind.

Just to be clear: I will not go to construct anything without getting a design with signatures, also a permission is needed and it's a long, expensive process. I have already talked with structural engineer and he said he will be able to find a solution, but won't go in to details until I pay. And I don't want to pay if it will be too complex or expensive to do.
From what I see this looks like it could become very expensive very quickly and in this case I won't do it.

I am here just to ask for ideas to better understand the complexity of this problem. I know inner side of the beam will lift the ceiling and it's wall above the window. That needs to be calculated and perhaps something extra done about it. Also I am aware this will add extra load on the wall's corner already supporting the balcony. That is not the topic of this discussion...

I am only asking about steel construction here, if it's possible with reasonable amount of complexity.
For example the engineer mentioned it may be possible to add a U-shaped UPE 220 beam on the side of balcony, which would make it almost invisible. However my calculations land at safety factor of 1.5, even if extra fixtures are added to prevent it from twisting.

So, can anyone comment if my calculations are correct and how should I calculate the load? As a point on a corner, or distributed via whole length of the beam? What is the maximum sag I should use when calculating the amount of steel this needs?

I'd call this a possible headache design job once the existing walls and foundation are known. I don't blame an engineer for wanting some assurance he will get paid and there is a chance the job won't justify the expense of the work, etc. So, keep asking questions here and my bet is you drop the idea after all the problems are known ahead of time and hopefully not during the work. No competent engineer here is going to give you a professional answer to your question based on what is provided. I can well imagine if you actually do some work to substitute for the column that it will look much worse than the column there now, in the mind of the average person. Ever hear of Rube Goldberg?

Exactly why I come here: want a qualified opinion on possible problems and work needed to solve them, also if my calculations are close to reality, as in this case it's an obvious no-go.
So, to help make up my mind:
* are my calculatios of loads and beams close to reality?
* what should I know about the foundation to see if it will hold? If it does not, there is no point in checking anything else.
* what should the beam counter to? I did some quick math to see if ceiling + upper wall (gas silicate) is heavier than the console and their weight looks similar.

I am not asking for drawings or end calculations, so don't worry, I will not run off to construct anything based on a forum post.
