Beautiful pool you have here indeed. This kind of location is a dream for photographer and a lot of club med pictures are made with this kind of effects : Pool / Sea in the background.
You have many possibilities :
1) Consider the "pool" as the main subject, which apparently is your choice.
In that case, it can be accepted to push a little the color saturation in order to make the blue(s) ( Pool, sea, sky )more "punchy.
Also a good photo can insist on the forms ( here for instance the edge of the pool ).
Basically i try to ask myself :
are the forms interesting ( in that case we have sometimes to rethink the composition ) ?
Are the colors vivid ? A good recipe is ask yourself when taking the picture to avoid extreme photoshop manipulation.
2) Consider the pool as a background ( and put models in the pool ). In that case this is not architecture, but portraits or fashion. Here the technique appears more demanding and you will need a good diffuser in order to lessen the harsh effects of the bright daylight.
Meter lighting can be useful also.
3) More dramatic effects can be obtained during sunrise or sunsets. I personnaly admire the work of Pete Turner who was able to have very nice commercial shots with your kind of elements ( sea, pool etc ) during sunrise , particularly tricky for us because light deteriorates as the sun gets higher in the sky.
