How wide a sunroom to add to 20x30 1.5?

[Lance]

Hey there John and all,

     I have me a gravel pad on my property up here in Sitka, Alaska and am preparing to build a crawlspace foundation for the 20x30 1.5 story plan.  First, imagine if you would the bedroom/kitchen side of the floor plan facing south and the bath/staircase side of the plan facing north.  (The 3DHA program will trade or mirror east and west but won't, unfortunately, make this north/south inversion).  Anyway, I plan to have a sunroom spanning the 19' 4" alongside the kitchen and dining area.  My question is, how wide to make the sunroom?
     A 14' wide sunroom with a 6:12 pitched roof is shown as an example in the sunroom plans, but this attaches to a house at about 14'.  Though I intend to build 12' walls for added headspace in the loft, my house still won't be tall enough to accommodate this roof pitch at this sunroom width.  OK, I need to simply adjust the roof pitch, the sunroom width, or both.  But before I do this I'm curious to know if there might be some ideas as to where a sunroom roof best attaches to this house's wall  (or extends from the house's roof?) from a structural standpoint, as well as what sunroom width and roof pitch might look best beside this cottage aesthetically.  For what it's worth I like the idea of the sunroom being nice and wide, but I'd be willing to cut it down to say, 10' if the roof pitch would be too shallow for anything wider.  (We've gotten a couple of feet of snow up here before, but that's extremely rare; it usually rains.)
     ...Partly answering my own question I see oakie-guy has a pretty spacious sunroom attached to his 20x35 cottage.  How wide is that one I wonder?  The two rooflines seem to line up nicely.  Then again, I think he's using 10' walls....
                                                                  Thanks for any ideas, Lance

I have a double-decked 10x24 covered deck and balcony on my 24x24 with 12' walls and 12/12 pitch roof----both under the extended roof---not exactly the same layout you are contemplating.  I think 10' is the minimum depth I would ever want---12 would feel much roomier especially if you are planning to spend a lot of your time there.

I would also try to go with a 12' deep sun room. At least this is what we will do for the 24 X 26 Solar saltbox we are building. Try to play in 3DHA with different roof pitches for the sun room. A 4/12 might work well for you.

Maybe you could built the roof in that way.
