About the 7 foot height, here's the deal:
The final layout will be done at full scale, derived from the original drawings. What I will do is scale up the drawings.
The method I will likely use is to use my compass to make a line several times the original on the drawing, then use that line as the basis for the final dimension of the building. I can adjust the scale of enlargements to make things a little bigger or a little smaller.
The drawings were made with a general scale of 1:24, but when I enlarge the lines to make the full scale, I may use instead a factor of 26 or 27. I didn't make the ceilings higher because it made the building look odd, I instead just decided that I would scale it up a little further. This is OK, because I don't mind having a slightly larger floor plan.
About the 2 drawings, they are very similar. The best way to see the differences is perhaps to put your eyes out of focus a little bit when looking at them. They are both the same design, just with different geometries.
There is 1 problem with the AQ design, however. The braces in the gable for the wall brace against the posts. With long braces such as these that is bad. It can potentially pry the posts out of joint. I will have to account for that or alter it in the final design.
