Greetings all. I am new to this site as my wife and I are working on designs for our new pool and backyard. We have a smaller than average backyard so we are trying to maximize space and add a pool, spa, lots of decking area and a covered patio. A few companies gave us designs that were fairly standard and kinda boring, then we talked to a builder that is known for awesome designs. His design blew us away, but separated the pool and spa, which I hadn't seen before. The spa has a catch basin for overflow and he says the water will move back and forth between pool and spa via underground pipes. Seems reasonable, but I wondering if anyone more knowledgeable than me can shed some light on any problems with this. Thoughts?
Hopefully these pics capture it all
