I am in the Process of building a new sugar house, it will have a 20x30 interior and a 20x6 shed roof for wood on the front Gable end. I have a 2.5 x10 arch and I built sugarhouse thinking it could handle a 3x10or3x12. I think it's big enough but I guess you need to consider if your going to have a separate Kitchen and Canning area, what kind of requirements you need as far as space for that, my kitchen is going to be 7x13, which in hind sight is probably a little on the small side. 10or 11x13 would have been much nicer if I had the cash flow to go 24feet wide.
Also I have 10' walls so it would be relatively easy to add onto each side if I want to some day. Good luck lots of fun building a new sugar house.
