Thanks for the prompt replies.
Wouldn't fancy having to open walls to reinforce the studs.
Front to back is about 5.5m. Would I be better to put, say 4 steels that way. I could put a stud across to support the trusses (I hope).
Sorry, I meant to write - I might not need to put a ridge beam...
Need a little advice before I go spending on drawings etc.
I have a timber frame house, end terrace.
Regarding a loft conversion, can I use steel for floor and truss support. Would the steels be ok sitting on the timber walls. The span would be approx 7.7m?
Some guys on the site I'm working...
