I need some advice regarding the fastening of the ridge beam that is circled on the drawing below.
The conservatory measures 7x4.5m. The glulam beam measures 90x315x4790mm. The glulam beam is pre-cut, so I can't recess it behind the facade without needing a solution that rests on the outside.
I aimed to avoid opening up the facade since we want to keep the panel inside. I know where the vertical studs are in the facade, but I'm not sure what's required for stability.
I was considering whether I could attach a 45xXXX to the facade for the beam to rest on. Do you think that would be enough?
There is a low roof pitch on the conservatory, so I suspect the rule will need to be bevel cut.
A beam hanger isn't feasible, I guess. Gable roof with roof decking and metal roofing. Snow load zone 2.
It might work with your angled beam, you need to check the load from the ridge beam and then size the screws accordingly. There are also joist hangers that can handle it, look at something like Strongtie, these also need to be checked against the load, the attachment to the existing facade is also critical, it must go into the frame. The bearing length should also be checked.
Unfortunately, parts of the facade must be removed in the areas where the roof meets the facade to make it tight. Additionally, the solution to place the support for the beam in the facade is not preferable since it ends up too far out from the wall frame. It also looks like there are edge elements against the house's plinth, which means you can't place a post inside the extension either. Considering the beautiful house and the new slab, I would reluctantly have purchased a new longer beam and made a correct support inside the wall.
I am considering doing some variation of this? And to attach the horizontal directly into the frame. The horizontal will be attached to three standing load-bearing studs in the frame. It should be able to bear enough, right?
Thinking a 45x220 in adapted length. What do you think about this?
@bossespecial We will open up the facade above the roof to get the metal behind the facade, but we really don't want to open up inside the sunroom since we like the panel as it is.
It feels like this solution would be the one that is quite simple to execute and looks good afterwards.

A bit difficult to follow what you mean with what you wrote above regarding placing a post inside the extension.
The slab for the conservatory is not cast together with the house's slab. There is an expansion joint between them if that changes what you wrote.
The outer standing beam on the slab is infinitely strong while the inner fastening hangs on screws, and I mean hangs, as the long beam is not set against a load-bearing frame but against the panel.
But, it still looks pretty good.
Is it possible to replace the door frames and put longer door frames so they reach up to the beveled beam, maybe in the same width, but a bit thicker rule?
I think it holds as it is, but I would have secured it with supports against the slab and considered more screws both in the beveled support and the rafters resting on it.
One doesn't need to exaggerate; if the original poster is concerned, it's easy to calculate the load-bearing capacity of the screws if you know the type and dimension.
A pillar against the facade wouldn't be ideal since it looks like the new slab is made with edge elements against the existing house, meaning all the load would come down on the baseboard and the cellular plastic.
