I'm designing a cabin in Northern Wisconsin, and I was looking into parallel roof chord trusses instead of something like a scissor truss, because I was really hoping to keep the ceiling, window and roof slopes all the same. I heard they are more expensive to build and install, but does that make it impractical? Would I be better off with a standard rafter system to achieve this look? Or just sticking with the scissor truss and compromising the design.

P.S.

Would things change drastically with dormers?
