Very interesting!
A few observations...
1. I wonder how it sounds?
2. Seems like a lost opportunity to build in one hella subwoofer somewhere.
3. That was a really odd pool; it looks like half of it was only about 1.5' deep?!?
4. That's a darn dangerous drop-off from the pool deck into the main seating area; I'm betting the building inspector would prefer some railings.
5. That's a huge area; it makes the screen look small. Doesn't the screen seem a bit high for the front viewing area?
Still, I'm picking nits. It is a creative and ingenious adaptation of the space.
But, you know, as a Swim Club guy, loss of any pool makes me sad.
