the same effect was achieved when the town planner staggered the side lanes or had them meet the main streets at a slanted angle. by deftly planning the town in this way, even drafts were avoided. another way of doing this same thing was to build houses out of alignment with their neighbours, or even whole blocks out of alignment with the rest of the street. this can still very clearly be seen around obere westheimer straße. such a thing was also done on untere westheimer straße, but the ravages of time have erased the effect.
