Anyone have any idea what the proportions are of the spans between the posts? I'm especially interested in the relation between the veranda (the outside-most posts) and the rest. Clearly, it goes: small, medium, large, medium, small. But in what ratios?...

Wouldn't you agree that most of the "aesthetic" of a building or a design comes down to proportions? But it seems so hard to estimate them.
