Architecture is a sub-culture just like anything else. There's plenty of software we love that is buried under a hideous UI, because we understand how the construction and operation of our beloved is unique in concept, function or influence.

Lots of aesthetics is to do with prediction and surprise, and if you don't have the 'perceptual training' you won't be able to make much sense of the art or architecture which defies your expectations.

IANAA but I imagine the "Technisches Rathaus" building is supposed to be a bit like what's supposed to go on inside a technical academy - scientific reductionism or abstraction. The design exposes the 'idea' of the components of the building (the steel poles, obvious floor layout, bringing up the 'foundations' to ground level) and abstracts away the typically visceral particulars (receding the windows, using only design-relevant adornment).

I think there are plenty of interesting buildings that look absolutely disgusting in context, but which I'd probably enjoy and be able to 'see' properly if they were grouped together in their own little town somewhere, because I'm not in a mode where I expect to see traditional architecture.

At the same time, if I never see those buildings, how am I to know what novel aesthetics I'm missing out on?
