The principle I showed in post #31 might not be so dumb after all. Three-hinged frames in the "wrong" direction provide larger gables than long sides. You can have as many doors as you want, and you get a very cheap frame system, which is very stable. You can get light from two directions to the loft. The most common form of three-hinged frames has sharp corners.
Just looks so damn stupid
No, but I need to think further

If I were building 3-400 square meters, I could definitely consider three-hinged frames. But for around 150 square meters, knowwhatimean?
It seems that you can probably make a single-frame truss at 8.4m without middle support, though the upper chords will be somewhat more robust.
Ah, look at that!
And a lower chord at 315 mm? I assume a glulam beam then?
What is beneath the lower chord? Another beam? Or is that just a detail image?
A bit hard to see what's on the image when I zoom in
It was an example drawing they had on arvidssons roof trusses, so it was a bit sparse with information on the drawing. But it shows at least that it is possible. However, as @justusandersson suggests a little. What you gain on one side you lose on the other, for example the upper frames take up a lot of space in the loft.

Yeah, but a 5x8 meter loft still feels pretty okay for a guest room or for a teenager
But it's not a particularly good type of truss to have over a workshop hall. Are you planning to switch to something else then for that section? With the same outer dimensions.

Yes, the idea was to try to have something else above the workshop.
If there were a framework over the workshop, then the wall height must be around 4 meters. Since the ceiling height should be around 4 meters for a car lift.
The ideal situation would be to have a ceiling height in the garage of 2.3-2.4 meters and then the loft above.
Then implement some other form of truss in the workshop where I can have my minimum 4 meters over as large an area as possible. Like open to the ridge or similar.
The alternative would be to have the garage part about 7 meters deep as we talked about with a wall height of around 2.4 meters.
And the workshop part 9-10 meters deep instead with a wall height of 3.5-4 meters and a different truss then.
That means the whole thing will look like a high workshop where you then build out with a lower garage. That means there will be "two different roofs & ceiling heights".
By dividing the whole into two volumes, you can more easily manage the project to make it as ideal as possible. Perhaps the framework could look like the image below. Keep it simple!

Not a bad idea at all! Just seems a bit expensive, feels like a lot of glulam?
It doesn't have to be so bad. Glulam is about three times more expensive than construction timber, but with 2.4 meter c/c for the framework, you can use rather slender timber for the rest. You need glulam for the sake of the large spans. It's also important to have the entrances in the right places, otherwise you have to make complicated exchanges. Additionally, you can get light into the loft, which makes it much nicer that way.
I have read this thread with interest. Since I have planned a construction of a machinery hall with the same type of structure, I am naturally curious about how you proceeded with your construction?
Best regards,
Johan
