Do you have any clues or such s to what the roof construction was? Was it purlin supported, ridge beam, trussed, what? This would also give us some clues as to its design.

For example, if it is somehow German, the exact configuration of the roof would pretty well point us to just where the carpentry tradition is from.

Also, certain roof designs would tell us it is probably not germanic (which right now I kind of doubt it is)

Was de eine ilüchtet isch für angeri villech nid so klar.
