I don't know if we've talked about this before so forgive me if you've covered this but do you know the history of your location? Possible trama on the land?
I don't think we've covered this topic yet. Well we are the original owners of the property, we bought the plot bare. But during the Boer War, my area (and the surrounding suburbs) did see some some action, apparently. So I don't know if that's playing a role in any way. As far as we know our plot was just an empty piece of land that we built on, I'm not sure if anything could have happened on there in the past. I'll see if there's a way to find out.
