Not for anything but for terrain. I could have built it myself, but there's a time in everyone's life when they'd rather pay someone for an oil change, rather than crawl under their 1994 Buick LeSabre. That happened for me 30 years ago.
The problem with platforms is that no one would be caught dead on them. No cover. These dominoes found at the local dollar store should be able to pass for bricks that never made it into the mortar.
