Greetings, all! First time poster but long time DIYer. Although, I'm afraid this is above my pay grade.
Our house is a raised ranch modular home (two pre-built halves connected on-site) sitting on a half basement. There is a ceiling beam that runs through the center of our home at the marriage line that is supported at both ends of the house. I assume our half scissor trusses for our cathedral ceiling rest on this. We're looking to add our addition by removing a wall that is currently supporting one of the ends of this beam. We want to avoid a post to maintain an open floor-plan with our cathedral ceilings. Our contractor proposed attaching a custom, beefy full-sized scissor truss to the exterior scissor trusses, but has not proposed anything to support the end of the existing beam. He thinks that it won't need to be supported as the new truss will take the load. I am thinking that existing beam needs support as there will still be half trusses putting weight on it, but maybe I'm wrong?
This is the wall we are looking to remove (with the two patio doors). Notice the beam on the ceiling resting on/in the wall.
This is the new floor-plan we are trying to achieve. The dark line through the center of the couch is where the existing exterior wall is.
So, I guess my question is, what are my options for supporting the end of this beam without a post there? A perpendicular beam at the height of my walls with a post on top of it supporting the beam? Sorry if I am not using the correct verbiage. Any help is greatly appreciated.
For reference, this is the exterior:
