If you are putting a wood deck on the left of pool, then that works out nicely with just enough height. If you are putting it on the short end of the pool then you need to dig out below it (on-grade decks are a rotting nightmare). If you are putting in a full paver patio then you need to raise grade - which is more laborious and expensive than you would think.

Some people are picky about their preference for wood decks vs paver patios directly adjacent to pools. Start with your space needs and where that will fit, all at the pool or split between fireplace and pool. Can't tell exact measurements, but I imagine you won't be able to have a continuous big area between them, a short walkway may have to remain.
