In my GH the north side is sloped and that, of course, is the space waster. The south side wall is about 5' high. I can hang plants all the way down the rafters to the wall and still have room on the benches. The peak is probably about 10' +. I have to use a short ladder to hang the plants from the re rods.
Here, the winters are relatively mild so a couple of electric heaters do the job on cold nights. It has gotten down to around 32 inside, especially last winter when we had a really cold one. But even Phals were not harmed.
As an aside, in MI when we first built the GH, it was covered with polyethelene. It used to keep me awake nights snapping up and down with the winds and me thinking that it was about to tear. Never did though.
The next winter we had the fibreglass panels.
I understand your concern about space vs. economizing on the heating costs. Are you considering buying the polycarbonate panels that will give you the maximum insulating value? I know they are more expensive but if they will lessen your heating costs it would be worthwhile to consider them.
Winter is not that far away for you. You need to get cracking on your new GH so you won't get caught building it while it is snowing.
