We are in the process of opening up the living room a bit. When a previous owner of the house in the '90s opened the wall between the bedroom and living room on the middle floor to make the living room larger, they left a post in the middle of the load-bearing wall. We now want to open it up completely by installing proper support.
An engineer has calculated that there are no issues with making the support changes. But there's one detail I want to discuss a little.
When they installed the post, they made it slightly shorter than the height of the edges, which means the floor joists are a few centimeters lower at the post than at the sides. The ceiling simply hangs down a bit. When we install a steel beam, we will need to lift that point and straighten the situation. Upstairs, there is a guest toilet where I have laid tiles, and I am, of course, a bit worried that they might crack, even though it does not rest on the same joists. The rational side of me says it shouldn't be affected at all since there are a few joists in between (up to 3 meters from the low point). But the house is, after all, connected.
I have attached a picture showing where the support changes end and the direction of the joists. The low point is in the middle of the support changes.
Do any of you have similar experiences? Am I worrying unnecessarily?
