I question logic in the article about stairs being narrow because there was a crane. There is a good case it is the opposite way around - that a crane. There was a tax on the width of the house, so having wide stairways was certain to increase the cost or reduce the useful space. My guess is that this led to narrow stairs, which required the crane in order to bring in things like lumber, beds and other furniture. And then windows that would accommodate those items.
