Why do penguins struggle with modernist architecture?

The refurbished concrete hurt their feet. The elegantly shallow pool was too shallow. The minimalist white walls were too white, and hurt their eyes. London Zoo’s keepers do not like to talk about penguins being “happy” or “unhappy” (it is anthropomorphising). But, says Jessica Fryer, team leader of penguins and flying birds at the zoo, some of the penguins’ feet became “so sore”. They developed a foot disease that, in its severest form, can lead to penguins being put down. It may not be possible to say whether penguins are “happy” or “unhappy”. But “dead” is definitely worse than “alive”.
