Hi all, I am looking to remove the internal chimney breast from my house on the first floor bedroom but leave the external chimney as it's a shared chimney. I believe a lintel or gallows brackets would have to be used. The issue is the neighbour has already done this on their side, so would it matter if gallows brackets or a lintel are used on both sides to secure the chimney? I know the best thing to do would be to remove all of the chimney, but the current neighbours can't agree to this as the house has been sold. We could ask the new neighbour but this could be some months away, and then there is the extra cost of removing all the chimney.
