That is indeed interesting; you have given an identical response to that from a local designer here. I thought it resulted from the structure really being foreign to him.
There is (now) a good reason why I can't do away with it: the foundations are well started, a system of plots with 1ft sq pillars and variable area base. The plots to each side of that external wall are about 3ft sq, whereas that under the wall is only 2ft sq. So, the load needs to be directed away.
It isn't entirely clear, but your objection to the strut seems to be on aesthetic grounds. To be honest, the strut does bug me somewhat, but more in knowing that it can do the job. It looked more correct when perpendicular to the rafters. So long as there is no structural reason to discard it, it seems to be the best option. Once the cladding is on it won't be seen from the outside, and it won't be tripped over because it only sits next to intended walls. Have you ever implemented such a structure in your builds?
There is another reason to keep it of course: its more timber-frame than just using the stud wall. :rolleyes:
