^I don't think it is artistic quality that matters to people. I think it is just that old stone or wood work etc. were endowed with what most people feel is personality and they feel connected to it. Our examples here in Toronto are relatively poor by European or even American Standards but the fact that so many people still care about this "low quality" stuff here in Toronto is a strong critic of contemporary architecture. Great examples of contemporary architecture are endowed with an overall feeling or expression but it is still mostly just made up of junk material that has no personality and no one cares about. Where natural materials such as wood or stone are used at least we get a sense of the natural expression and personality of the material.
I can appreciate a Foster building for instance if it has a strong sense of form and expression and I think most people would agree; However, the vast majority of people feel instantly a connection with natural materials, and historical architectural details that invoke the idea that someone's hand, time, and labour went into creating it.
I am not making an argument for historical preservation of the building in question here. I am just making an argument against dismissing even mediocre historical detailing as significant. Even mediocre architectural detailing is significant because no one puts the time, money, and effort into creating it today.
