A condo? Usually for high rise, the separating walls between units can be load bearing, thus it is not hackable at all. You risk undermining the structure of the entire building if you do so. If the wall is indeed load bearing, the upper units can collapse upon your unit since there are nothing holding the concrete slab at the top.
Best people to check with are the management office, but from my 2 previous condos that I have stayed in, none allow such hacking, i was not even allowed to move a door to another wall for an adjacent room.
Good luck
