The chimney strongly suggests there is a fire place. I am not 100% certain but I am told that there are building regulations that apply to a fireplace in a wall on a property boundary. This from a situation when a fire place in a renovated cottage was opened up and open fires lit. The external wall became hot and was seen as a hazard to the neighbour's use of their garden. I suspect "hot" was more like very warm and may only have affected plants growing on the trellis fitted to the wall. Never the less building control were informed and the fireplace had to be modified.
Very interesting...thank you. If this does happen i will be taking it further. The council know its there. Would i need to inform building reg department or would the council automatically?
