Fit for purposes

[Bassim]

I have tried to use "fit for purposes" in my sentence. I am wondering if it is grammatically correct.

The local authorities have decided that the old music hall is no longer fit for purposes and they are going to build a new one.

To me, it sounds much better with "no longer fit for its purpose".

my vote: no longer fit for use
