I would like to build a swimming pool on the ground please receive adequate guidance length 20 meter

my home behind the house to the ground and filled with soil about 1 m and then built swimming pools in the above two meters deep on the second floor so that you can use a I do not know swimming pool and a house to share that wall 20 meters long and 3.5 to thickening of the number of layers is enough to withstand water pressure ??????

is really a complex thing

You should put the issue on the building type, instead of swimming classes.
