Hey Steve.
Welcome aboard. I think you'll discover this little forum is a great find.
Folks here will probably need some additional info about your project...
What's your background as far as construction?
What will you use the building for?
Do you want to hew, or are you buying sawn stock?
Any particular species of wood you are planning on using?
Do you need suggestions on raising or joinery or both?
Framing styles: purlin roof or common rafters, etc?
I'm not the expert here, but these are some good starting points.
Best and welcome--
