turning attic space into room possible in this situation?
 

I have an attached four car garage with an angular roof that is flush to the side of the house.

Inside this attic are multiple joists that support the roof.

To access this room, I envision a door to be placed on this wall above the second floor landing with a bridge to connect the two floors.

Here are the framing and rafter plans for what its worth.

Would this be feasible? Thank you!

maybe. . .
 

Measure the deflection at midspan for one of your attic floor joists, then measure again with you stepping on the joist at midspan.

Is it a modified King Post truss, as shown in this link?

You're in the Ozarks? I'll need that info to look up your normal roof loading.

I am not an expert but I guess it can be possible just like what it looks like on your floor plan.
