Was down the block yesterday and as there will be a bit of excavation to a hill back left of the block, my daugher suggested we get one of those flat tall ones that could be used as the retaining wall and cover it with trellis and creeper. We still have to get a building permit so the bldg insptr will know and probably will be designated on the full working drwgs when we get them. Want to go hell for leather on bldg this house so trying to do a bit of foreplanning.
