The platform and edging are two seperate assets. If you search username nexusdj and platform edge, there is a range of 15 different edges. The surface is by tmz06003 but I can't remember the name, something like tarmac platform surface. There are several widths. The wall is built in. If you type 'brick' in the spline tool, I think it's brickwall 8ft but I could be wrong, I'm not at home right now.
