The wall will only be 4 high, the other bricks are there to get them out of the way.
I've finally just about levelled off the main area which will be planted with buffalo grass - the grass partially visible grew in under a season from a few cuttings so it wont take long. The sand left-over from under the long-removed pool will top-dress the grass.
Looking down the yard, on the left is a large garden bed - which will be herbs and vegetables. It gets full sun in winter and most of the day in summer.
Behind that - under the Golden Rain Tree is to be paving, made from the old bricks stacked up next to the house. Unless they end up being too ugly.
