Houses are built to live in, and not to look on: therefore let use be preferred before uniformity.
Before I forget what i thought, I'll just write it down:
"Unless houses are built completly underground or invisble, they're part of our environment; thus we continously are forced to look on them. I prefer aesthetics and beautiy over uglyness. Uniformity as the only requirement is not enough.".
Interestingly, the book I read only contained the quote up to the colon and at least partly misinterpreted the quote by omitting the demand for uniformity.
