I wanted to build a second level at Sims4 but for me it is not that I'm building a second floor. I've already looked at YouTube and everywhere but I can't find a solution. Does anyone know why?
Do you have a staircase that goes up?
No🤷🏼♀️must you have one there?
Yes. So you make the first level and then the desired stairs at the desired location and then the second level is automatically built
