In other words, which of the 3 options on the drawing are correct? Or all of them are fine? Please comment.
Thanks for this explanation!1. is fine, 2 and 3 redundant (why use a beam to support joists when you already have a wall?).
The main beams don't have to be 'closed up'.
You are right. The reason I put options 2 is because that's what our builder suggested, so I thought you need to have beam ends restrained or built into something solid, hence option 2. Since on the left - it's the end of the house (free space) - I thought option 2 is a minimum to have.Is the question about whether the ends of the beams need to be restrained or built in in some way?
because that's what our builder suggested
Design gives you rooms and windows layout and materials to use but not such details as beams and joist location, does it?Maybe you should get some professional design input
He is an experienced builder with a few completed loft conversion projects (verified) and a number of very experienced sub-contractors (like roofer and joiners I've seen and spoke to) do the works. He doesn't do anything himself but leads the project.leaving you and your builder to scratch your heads over the other elements like insulation etc.
What do you mean by "attach them to neighbours wall"?Thanks Johnny. If the option 1 is OK and the beam ends can be free-hanging - why attach them to neighbours wall on the other half of the loft?
On metal hangersWhat do you mean by "attach them to neighbours wall"?
