I started working on this at the beginning of April, First I had a lot of plants to move, water iris,sun drops,gladiolas,cactus,hibiscus,and sedums. The top of the enclosure will be at ground level.I still have about a cubic yard of dirt to remove to get it where I want it.It measures 6ft x 12ft and the side walls are 13in high.- slowly but surely it's getting done- Len
