It is of interest to consider the relationship of the German style to, for example, the Anglo-American or even the English styles.

In Essence, the older German style of the earlier Middle Ages, Ständerbauweise, is virtually identical to these two styles, with a few variations as is to be expected. In fact, American timber framing is in German referred to as Ständerbau.
The general method of framing is pretty much the same idea. Walls are framed as one mass, in some examples being rather bent-like in configuration. Tie beams are used, in the north taking on a drop-tie form and in the south a form similar to the English tie. floor separations are established by means of horizontal timbers mortised directly into the posts, at times with long tenons extending through the post to the exterior where they are wedged.

But in the 15th century the Germans totally reinvented their frame.

The question must be asked, why did they make this change from the style that was prevalent across most of Europe? What advantages did they see in this? Why did their culture decide that this method was superior, while everyone else continued on with their various versions of the older system?

It must be noted that the Ständerbau style is not a style that was so much passed around among everyone in the middle ages, rather everyone developed this style from its immediate predecessor, the earth-posted frame, which is something that was inherited by all of the people who came under Germanic tribal dominance, hence the remarkable similarity between early medieval German, French, English, Low Country, and Scandinavian framing.

It should also be noted that everywhere where jettied buildings were built, they seem to have developed a style similar to the German Rähmbau, but the older high posted style continued in use in other bu8ildings and in the countryside, whereas in the Holy Roman Empire it passed out of use entirely by the late 15th century in everything but barns.
