When Dave and I decided to build here in Florida we originally went for the first floor only plan with a pool and screened in lanai. Then talking it over we decided to scratch the pool for now and add the second floor since later down the line we could never add a second floor (HOA rules or something). It just made more sense to have more space and could add a pool later. Well our backyard does not look like paradise (like my parents) but kind of like a very sad playground with a lone hammock as the only swing.
I know you folks up north are thinking wtf is this talk about pools in April, but it's been in the 80's here and there lately and Dave and I are already talking about beach weekends. To me 80 degree weather is lay out weather regardless of whether the pool temps are too cold or not.
