Can I make it? Because mob farm usually big, and I don't have enough block to build it (I'm playing on survival). I hope I can make it and it will work.
It would work if you pillar up more than 128 blocks above the ground so all mobs outside the mob farm despawn. Which you would want to do with a normal sized mob farm as well unless you've lit up all the caves within 128 blocks. (That's your position, the mob farm could be lower as long as it's close enough to you.)
It would be slower than a big mob farm but if it's the only place mobs can spawn then they will spawn there.
That's assuming you're in single player or alone on a server.

Just dig up more blocks!

Just testing.
look up gnembon mob farm in youtube, that's pretty much the standard design for starter mob farms, that's as easy as you get
