Other folks had also questioned the rectory scale, so I went back to the original model with a carpenters eye (I worked on a house construction crew in my misspent youth) and realized there was no room for ceiling joists and the rectory was still too narrow. I think the proportions now are more in keeping with the real thing. Other thing was that the wood shake roof was too flatish, so hopefully what I've got now is more typical of an aging wood shake roof in need of some repair.
