Pool Plan

Here's a photo of our yard, with the plan for the pool drawn on it (using my extraordinary graphic design skills) - after 3 consultations with Steve, from Mr Carlos Pools (sometimes it's Mr Carlos and Associates).
The yard slopes in a slightly tricky fashion, so the pool will be slightly raised above the ground, and dug into the ground. On the back left corner there will be a wall about 2 feet high, then a gap between the pool and the wall (we can't do anything with that gap, 'cos the wall to the neighbor's is a bit feeble, and if we fill it in, there's a chance it will fall down). The D shaped bit will have three steps going into the pool.
The nearer side of the yard is fairly flat so that will be level. The soil that comes out will be used to make a slope from the left hand side, going down to ground level.
