After the hall has been completed and the sub-plots unlocked, can it be razed?

I'm wanting to eventually upgrade the t5 GH to a t6 (and MOVE it from the original position on the plot), but I wanted to know if it was possible before I started collecting the extra resources needed.

Has this been addressed before? I couldn't find any threads that discussed this specific issue. If it has, just point me to the thread.

Any answers would be much appreciated.

Thanks!
