Your plans seem expansive and maybe costly. Id spend just a bit more and get a proper professional plan done.

horizontal anything is a no, the gap would have to be so small it might as well be solid. yes the vertical cable might pass but you are not allowed to be able to squeeze them together as then the gap distance is non complying, The safest one is the solid section PCA pool fence, or glass, or solid, to 1200 mm in Queensland, no greater than 100 mm off ground, and gaps not able to be manipulated, and to stop that you have to have horizontal section in the cable type, which then do not comply, cut metal screens if complying is OK. I would question the void, and if you know the reason for the void, than solutions will be able to be worked out, now we are asking why? Pools in adjoining yards are acceptable with pool fencing complying on both sides, no void is required. so the void sound a bit iffy, unless it is something to do with storm water, or a building requirement, so ask the question why. Pool fencing can be awesome.

I would like to reduce the width anywhere from 80' - 90'. The land is completely flat. We have a lot on the corner, so the main roads would be on the right and bottom. I picked this layout because I liked the privacy it gave our (to be put in) pool. There are existing neighbors on the left and soon to be neighbors behind us. We have a large family so I want to keep all of the house space/ bedrooms etc. Ideally I would want to move the 3 car garage somewhere behind master suite (not sure at which angle). I just don't know how to completely flip the right side of the house and still make it work, because I like the idea of having the master suite able to walk right out to the pool. @oklouise @Black Bamboo @dreamer @Kate @User

I was going to suggest that the shower and hanging for togs and towels be placed in the red zone using the pool house plumbing. It looks great where you have it but it should have somewhere for the togs and towels as kids will use them several times a day in hot weather. If the Pool House was a POOL house and open to the pool would that mean you could just fence it and the pool together, but I guess by being multi function that changes the rules
