We have recently moved into this property and wanted to remove the rotting decking at the back of the house. After we removed the decking, we found that there is a sewer grate quite close to the patio doors. I have attached a picture. I realise that the perspective is difficult to get but, hopefully, it gives an idea of the problem. We need some form of platform and steps coming out from the patio doors, but have no solution due to the closeness of the grate. We know that we can get grate coverings that can blend into the monoblock, but that does not really help with the problem of getting out of the patio! Any suggestions would be greatly appreciated! Thanks.
