I'm not sure if I've posted this before but it bears repeating. NAHB put out a white paper awhile back on a system for framing houses with all the appropriate structural backup and calculations. What they were trying to do is decrease the amount of framing members and time taken to frame floors, walls, and roofs.
In short, their ideas were to place everything on 24" centers so the roof trusses lined up with the wall studs which lined up with the floor joists. Is what that allows to happen follows:
1. Single top in lieu of 2
2. Windows could be framed with no headers as long as they remained 22.5" width
3. Rim joists could be reduced in many instances by using the plywood as the stabilizer
4. It also goes on to have a couple different ways of doing interior to exterior wall connections and framed corners
5. And some other things that I can't remember - will have to pull the book out again.
Is what the study found was that a home with 2000BF of framing material could be reduced by about 25% and a reduction in manhours of about 30%. (percentages are off the top of my head I'll double check them)
I've actually used this method on a small addition to a home (600sf) - actual SF cost completely finished was around $47 / SF.
Has anybody else dealt with this before or seen someone build in this way?
