Yes we did!!! Built a pool hanging off the edge of CAMELBACK MTN. Had to faux the underside of the pool to look like granite!!! WTF, OVER?(LOL!!!!!) All building materials were hand carried up a MTN GOAT TRAIL!!! (flagstone,block,mortar,paint,tools etc.) The house is the highest up on the east side of the mountain! The job is almost finished. The negative-edge pool is quite impressive, Glass tile throughout, Mermaid & sunburst mosaics are amazing!! Climbing up and down the thing isn't making me any younger
