School problem (auditorium)

My school's previous principle wanted to make a auditorium.
But he had to go to another school before he could.
I think he did everything he could do.
Last year, my previous principle asked the shop owners
in front of the school, to cave in their shops to make a auditorium. But they refused.
So, he decided to use the old library building, but he realized we don't have enough money.
Some say that we should leave the building, because we study many things there. There are
Math, Jump rope, English, Art, and Korean classrooms there.
So maybe leaving it will be better, because if we make an auditorium, we will lose all the classes.
What should our school do???
