Cris You do realise that you don't have to have a fence or wall etc to comply with the law? As long as you have one of the safety devices that conform, ie a fence, or an alarm or a safety cover thats OK. My pool is in a similar position to yours so we're getting an alarm ( yes, I know the problems!) and not letting our gite to anybody with children under the age of 5 years, just for our own peace of mind. Good luck with whatever you decide.
