The building must be appealing to the eye:
"a building should meet obligations of commodity (utilitas), firmness (firmitas), and delight (venustas)."
-Roman Architect Vitruvius
Thus, since the focus is aesthetics, a good example would be the Somerset Area in Orchard Road, Singapore's Shopping District. This place needs to be attractive and happening
The Fullerton Hotel in Singapore is another such example
The last example is the Museum of Natural History in the USA
