I once read that the order and symmetry of the exposed woodwork of timber-framed medieval and later houses revealed something about their age. Broadly speaking asymmetrical, seemingly (though not in fact) haphazard wok was usually an indicator of early work - say, the fourteenth or fifteenth centuries. The more orderly, symmetrical timbers that were often arranged to form patterns and sometimes include ornamental quatrefoils and such were invariably later, usually dating from the sixteenth and seventeenth centuries. By that reckoning this photograph taken in Lavenham, Suffolk, shows some reasonably early timber-framing.
