Need your advice about a property I am due to purchase over the coming weeks. It’s a terraced property in London and one of the first things I want to do is remove the chimney breasts from the downstairs dinning room and the upstairs second bedroom. Our neighbours who share the wall have removed their chimney breasts already and I have spoken with the local councils buildings regulation officer who assures me gallows bracket support in the loft will be enough and I will not need to put in a beam/RSJ support.
Do I need to apply for a party wall agreement before starting the works? If so how long does this take as I am keen to start asap. Any advice/experience appreciated.
