my pool construction - part 4

This idea looks cool I was thinking about building something like this eather as a swimming pool or a large Kio pond. There is also someone on here who built a 10,000 gallon fish tank this way with two giant viewing windows on the side of it.

whats with the block wall why not gunite it like every other pool i think its cheaper unless you still plan on guniteing it
