Flat Grade Affects Your Options
This deck was built on a flat area and so it had to be elevated well above the rest of the deck up against the side of the home.
The first floor of the house was much lower and so the other deck was on grade or just above it.
Sloped Grade Can Be Helpful
If the pool is set into a dug out area or you can take advantage of a natural slope in the land you could be in luck.
A slope will allow you to build around the above ground deck in a
way that can look very natural. In fact, it can even come close to making the pool
appear as if it were built in-ground.
