Drums are hard..best is a complete new blockwork wall inside the
existing, no windows, and air con system. Also consider a block and beam
false CEILING.

You're thinking a lot bigger than I am...

You will also need to line the blockwork with egg cartons or similar to
break up reflections.

Sadly, egg cartons don't - despite legend - have any acoustical
properties worth making use of.
