Anon (didn't realise you were Ella - I always agree with your posts, for what it's worth!) - I don't really know much about architecture; my Dad is one, and now works in built heritage and preservation and I grew up around a lot of architects. My own knowledge is pretty scant.
From my own point of view, the work of many architects isn't necessarily aesthetically pleasing, at least initially. It is often very original and ground-breaking though, and often only once a style has become accepted and even familiar that it actually becomes appealing to the eye.
One tower block is the same as another, yes. But the first tower blocks were remarkable in their design, engineering and foresight. Subsequent ones in the way the various techniques were honed. I feel like this is stating the obvious - apologies.
It is very subjective. I really don't get Gaudi at all. :-/ Yet so many people jump on the bandwagon adore his style. The thing is, to me anyway, architecture is about so much more than just style, it's also about how we live and how we see ourselves. Architects like FLW designing bungalows and revolutionising the way families exist in their very habitat, for example. So what is considered 'good' isn't just about the way something looks, but how it works as well.
But yes, these 'conventions' and standards probably were defined by men for the most part. Wholly though? I doubt it. Do architectural styles dictate fashion, or does fashion dictate style? Art Deco, for example - who influenced who (whom?!). This style emerged in the 1920s when female fashion designers were coming to the fore and I think it's fair to say that there was probably some mutual appreciation going on.
