Hi
1930s Semi Detached House.
Looking at extending the lounge area by 2m. This will entail knocking through and a beam installing to support the 1st floor. In order to maximise the size of the room I want the beam to rest on the smallest "stub walls" possible. So, is there a minimum length of stub wall the beam can rest on?
Ultimately I know a SE will need to prove any alteration with calcs, but just wondering if there is a standard / recommended?
Also, if I wan a loft conversion, will this affect the above?
Thanks in advance.
