Thanks guys. The timber just turned up and I knew it would be heavy but my word they are. I'll therefore have to draft the brother-in-law in to help.
I have also been fortunate in that they were not cut to size as the chap couldn't be bothered. So I might be able to mortice in beam method.

Advise about loose tenons and dowels have been given. Another non purist option is the big screws (up to a couple feet long) log builders here often use.




Consider using a post saddle rather than the rebar to hold the base of the post. It not only locates the post but prevents uplifting in high winds. It also holds the wood off the brick so it doesn't rot out as fast.

I got all excited then. Thought someone had found something instead of stainless steel coach screws but unfortunately I don’t think the above will be suitable in green oak. Great for other timber though so I’ve learnt something today if nothing else. Thanks Inspector 👍🏻

What I didn’t make clear is that with the upright post being 2.4m and the beam of 150mm resting on it (2.55m) that gives me enough fall for the flat roof.
With the mortise in beam method I lose 150mm.
The only other way I can see is to increase the height of the pier which would be a PITA for me.
Are fixings an absolute no no with green oak?
Don't start from here (old joke).
From my experience, iron of any sort and oak just don't last.
How much of a PITA is extending the pier?
Bodge? a foot of oak jointed into the post and beam? (You'd learn a lot about oak that way!).
Can you address the fall requirement (somehow).

If the 'roof' structure is really heavy (another bodge), a copper / brass / bronze spike into post and beam
(Ask if these alloys react with oak, I don't know).

How about bridle joints and a pin that goes 100mm up the middle. You can buy oak pins off the internet.

Some of those screws are ceramic coated for use in pressure treated wood. I'm pretty sure they will stand up to the oak. Contacting one of the sellers or makers would confirm it. You could always work with hot dipped galvanized lag bolts/screws.
