Hello
Following on from my last question about a split purlin I did some digging on regulations.
The length of the purlin is 4m. The size of the purlin is 270mm x 70mm.
Looking at the tables this isn’t sufficient? In fact nothing seems to allow a clear span of 4m. House is mid terrace built in late 1800s. I expect the whole street is like this though.
Am I reading this incorrectly?
