Why not bigger so you can fit more than juts a pool table, will there be heat and AC?
Why not 5" corner and 5.5" side pockets
Bro has so much land he's just randomly dropping buildings all over the backyard.

First a lawn shed, then a swimming pool, now a pool room... next it'll be another garage, a basketball court, or maybe a pickleball court. Serious question though, how do you get to the pool room when it's raining or snowing without getting wet

?
Can we see a picture of the whole property? I'm curious how it's all laid out. Did you actually have a master plan, or did you just point at random spots in the yard and tell the contractors, "Put it there!"?
