Hello!

I am in the process of building a new home with a turnkey contract.
A parallel roof is planned for the house and I've received two alternatives.
A parallel roof was the solution because I wanted high ceilings, even in the hall.

22-degree angle for option 1 and 12-degree angle for option 2.
Does this mean there is less height with option 2 with a 12-degree angle?

I also wonder about the lines in the middle. One option had lines in the middle and the other had just one line. Do you know if this means that the beam is thicker or larger?

Option 1, according to the drawings, involves a beam at the ridge, with a post in the middle of the room.

Option 2 has free-spanning roof trusses that do not need to be supported with a beam or post; however, they do not provide as high a ceiling.

Thank you so much for your answer.

Option 2 seems to be the one in question. A 14-degree angle is standard but now it'll be a 12-degree angle instead. Is a 12-degree angle very low?

It doesn't seem very attractive to have a beam in the ridge, although it's nicer with higher height in the house, or what are your thoughts?

There is a big height difference with a cathedral ceiling compared to scissor trusses, but there should be a price difference, scissor trusses are usually the cheaper option.
 
Most houses probably have a 0 degree angle and 2.4m ceiling height, so this will feel more spacious regardless.
You end up at 2.5m at the outer edge, and 3.5m in the middle.

I would probably also aim for option 2, maybe mainly to avoid the post, but I also think it looks nicer without the visible beam.

The difference in height to the internal "nock" will be about 90 cm, but then you will have a post in the middle of everything, which you avoid with the free-standing solution (and a visible beam). I would definitely choose the scissor truss to avoid the post. It will still feel spacious with that ceiling height.
 
Option 2 is the one that is relevant and I share the same opinion as you.
It doesn't look good when a post goes in the middle.

Thank you for all the responses, I truly appreciate it.

It is possible to set two posts, one on each inner wall, which should also reduce the size of the glulam beam.
 
Could it be an lb house, option 2 absolutely
