we are going to remove the chimneys in our 1930 s semi both are on party walls (we have agreement in place) one in the dinning room going through to the back bedroom and one in the lounge going through into the front bedroom then both joining into one in the loft and out to the stack,we will be removing them one at a time to coinsist with other works ,we have no access to the breast in the loft as the loft has been converted so we want to do lounge/front bedroom first we will be leaving apx 8 inches in the bedroom from the ceiling down and then plan to use gallow brackets and make a feature ,can anyone tell me the process of doing this as in how do we support the chimney that is staying while we remove below and fit brackets ,many thanks
