Next to the rather odd free standing wall there are two areas of gravel. We decided to use the stone from the fireplace which we removed to make a raised bed with two levels.
Under the gravel was a layer of blue plastic. No idea what it was for originally.
Rather than clear all the gravel I just cut away the piece from under the new bed.
First line of stone.
Tried to follow the curve of the wall.
No idea what the paving slab is for. It just sits on top of a brick pillar. Too hard to remove.
Filled up with decent gritty compost and soil.
Used some old bricks to raise the level of the back half of the bed.
Central wall built.
Planting begun. I filled the top layer with Silver Saxifrages.
All planted up and covered with gravel which matches the rest of the area..
