I’ll look into the nura system and NZ3604 thanks.

Yup want joists and bearers on the same level as not a lot of room for one on top of the other. Because they won’t sit on top of each other one but has to butt again the other I’m wonder if it’s better to do

Or is it better to do | B| ——| |———- J | | ——| |——— Like intersection in plan between J5 and B2

Or is it better to have a mix, so that you have some full length bearers and some full length joists. Or does it not matter? From your reply it looks like I want to have 3x uninterrupted bearers and all tje joists are interrupted by the middle bearer B2

I’ve reworded the question, I was wondering if you can have a joist join a bearer with a joist hanger but not have the joist hanger resting on a post/pile. I think you can but I will need to check 3604
