Looking to join together existing sliding doors and separate door with a set of 3.5m bi folds. This means taking out a 300mm width wall between them.
I assumed an RSJ would have to go in but have had one quote who said they could install a catnic to this as they have standard calcs for what they could take etc. My question is, is this ok?
Also, assume I should ensure building regs are done for this?
