Classical and in a sense neoclassical architecture literally stood the test of time.

Always seems weird to me that "classical" is stark white columns and sculptures. The original Greek buildings were quite colorful, it's only the intervening millenia that are responsible for wearing away their paint.

It is a fact they improved with prolonged exposure to the atmosphere and UV light.

Many of the architectural styles didn't get enough time to stand the test of time!

"Man fears time. Time fears only the pyramids."

They have terrible natural lighting. Wouldn't recommend living in one.

Not to mention the how little usable interior area they have.
