The dimensions of the building are 8m long by 6m wide. The pitch of the roof will be 8/12. It will be an open ceiling, with some sort of steel roof plates.
My initial thinking is to follow the same principles in log house building for the wall plates e.g. I would imagine something like 15cm lumber with half lap joints, but watching videos I see a lot of modern construction using much smaller pieces. What would you use?
Securing log wall plates
I would drill down into the top row of bricks and cement in some half inch threaded steel and lock the wall plates to the bricks like this. Is it suffice?
I have only really learned about log building, where tie beams are made of whole logs and they join into the wall plates, but looking at a lot of modern construction it seems they don't even use tie beams and just have ceiling joists. Are they making these ceiling joists act as tie beams?
Modern construction seems to use a lot of these metal plates to join rafters instead of traditional joinery.
When I demolished the roof on the brick barn, the rafters had birdsmouth joints that sat on the wall plates. Are these birdsmouth what you use. How are they secured properly?
What do you use and why?
What sort of size lumber do you use, and how far to space apart the rafters?
what is your preferred method of joining the rafters at the top?
Do you bother with joints or do you just use a whole bunch of different metal plates/anchors with nails?

When I said 'Steel roof plates', I meant tin sheeting. Sorry - what do you call them? Again, I would love to get a froe and make shingles, which is what I'm hoping to start doing for the log house, but unfortunately I think tin roof is the cheapest and easiest for me to install this time.
