New neighbours next door ( not attached ) are having works done they have knocked down their existing garage outhouses and kitchen and are rebuilding on existing footings. I have made enquiry with council planning dept as I think need some sort of planning permission / building regs check apparently their builder says not ? Anyway main problem is where they have knocked garage down there is now access all along side of my property and I have asked the builder to block off and secure when they are nit working with temporary fence or panel but they have left it open. I feel really exposed now we live in a culdesac but it’s leaving my property vulnerable. There are 2 diggers in their garden and no back door so anyone could wander up the side and into their house or mess around with diggers surely this is a breach of health and safety? Any advice welcome thanks
