raised cornice for rafters
 
I am in the process of designing a detached garage with apt loft above. Rafters to rest on top of raised cornice (3- 2"x6"'s) on top of ceiling joist for a little extra height because I need all the extra room I can get. My first question is: is this ok, shouldn't go any higher w/ the raised cornice right? The only other option I can think of to get more room without making entire structure wider is to use 10' studs on first floor but have a 9' ceiling w/ jacks supporting joists. Also with first example of using the raised cornice, when drawing living space upstairs (12:12 pitch) I am measuring 1' rise to 1' run measuring from outside wall across floor and from floor to rafters. I figure the 3-2x6's will offset the amount I am losing for rafter notch cut, finished floor and ceiling. Hope all this is making sense and thanks for any help, I can provide more detail if needed.

Why not a gambrel style roof? Or even a hip? A whole lot more room would be avalible.

You lost me on the hip having more room, there would be less room in a hip attic than a gable attic.:)

Roll Tide, sorry, couldn't help myself there.LOL

I dont like the look of gambrel roof on garage.

another way is to frame a knee wall onto the top plate that goes 6 to 12" above the top of the joists. build walls, set the joists, and then frame the knee wall right next to each joist with a double top plate on the knee wall and then frame the rafters. this could be better than laying down 3 flat 2x's

actually, after more thought, I think i would rather widen structure rather than have cornice work sit too high from ground, top of windows/doors, also it will have a lean to porch and dont want that raised up to high also... so is 3-2x6 too much of a raised cornice, structurally speaking?
