Patio & Pool
Create a wall of stone and place it on the east of the pool. This can be the visual barrier on that side. Since it is the top of the hill, it would not have to be too tall.
Along the driveway or entrance to pool on the side yard, porous pavers and also lighted low-voltage pavers would be great.
I like how there is a counter perpendicular to the kitchen with stools.
The stone/tiles around the pool and the steps leading to the pool.
A great slide!
