I believe this shouldn't be an issue as there's no hacking involved, but best to check with management on this. I know in a 2+1 unit plan for Sunway Velocity Two, there was a diagram for the studio unit where the door accessing it near the foyer can be bricked up and you can hack a section of the wall in the middle which connects it to the rest of the unit. The latter part is highlighted as a 'block wall' which means that you can only hack that section, not simply anywhere.
