Ah yeah - someone in the know (can't remember who) told me on a forum once that there was a fairly influential chap in the world of 'small model buildings to put toy soldiers near' during that early 90s period who was a big advocate of under-scaling buildings. He was specifically talking in reference to those Scotia domes (that you pointed out to me where originally for Kryomek), but perhaps he had an influence of the grenadier ones too. It works well with your selection - I think they call that 'non-standard construction' in the world of town planning!
