If an rsj is already in place, for example if the kitchen at the back of a semi detached house has been extended to the side by taking out part of the side wall on ground floor, is it possible for the supporting rsj to be removed and replaced if you wanted to do a back extension and needed a longer different steel? I can't seem to find any info on if this is possible. I.e. how can this be done without the walls above falling down before you get props in?
Likewise, if a semi detached house had already had the back of the house opened up, first with a steel for the back reception room for a conservatory and then later by removing the back wall in the kitchen for a small extension, is it possible to replace both of these with one long one. The reason would be in order to take out the wall in between the kitchen and reception room along with the pillar that both steels sit on. Can it be done?
Thanks.
