We bought our 1960s house nine years ago and subsequently found it used to have a well in the back garden, it was discovered about 40 odd years ago. The house sits on a plot where a large Victorian villa used to be. I’ve never really thought about it but We are going to sell next year and I’m just wondering, do I need to mention it, I don’t want to put of prospective buyers!! It’s not a large house or garden. It’s covered in grass now and has a plum tree on it but if you’re digging there and dig about ten or so inches you can feel the concrete.
