Condo, please ask Management office first. Some building with many walls are supporting purpose.

Usually when you see one room in an open space is because the room is build to hide the pillar. Looking at your image, i am guessing there are either pillar(s) to support the building or maybe the entire wall is use for supporting the entire building.

You need to consult building Engineer. Don't take any of the forum-er word. If collapse not the forum-er going to suffer/die. Is you.

Possible, still need to have a proper engineer to look at it. Normal contractor will not know what is what. Especially dealing with high rise building.

Do you know the developer? Maybe you can contact the developer for guidance or maybe ask them introduce you to their Engineer.

My meaning of "look" does not only apply to visual, is inspect and check.
