Location?

I hope your pool is enclosed. And heated.

Good luck with finding a contractor. You do realize this forum is worldwide, right? (As you can see, Babs is in New Hampshire, I'm in Missouri, I think Sophie is in the southern U.S. somewhere . . .)

I did a search under Houzz professionals for “pool cabana” for the Cincinnati metro area and got this list:

https://www.houzz.com/professionals/s/pool-cabana/c/Cincinnati%2C-OH

Each will have a portfolio of work, recommendations from customers, and you can contact ones whose style appeals for additional work samples and ask for further references. That may be the best you can do here, or you can try talking with local friends, neighbors, and acquaintances.

I would just start seeing what comes up when you google "[location] landscape design build" or "pool landscape [location]". It's not like there are specialty pool cabana companies, and they're usually part of a larger pool & landscape project. It's been 20+ years since I worked in that part of the world but I do know there are some pretty stellar landscape design-build companies, I'd start there.
