[BIMBAM]

A building ends up ugly if:

- It uses tacky and displeasing proportions that run counter to traditional theories of aesthetics. Alot of faux historic new builds make this mistake.

- It uses crappy materials in an uncreative way which makes the building look bad.

- Its artistic statement is offensive. People don't realize that all architecture is a work of art, but even if they don't it still effects them emotionally and subconsciously communicates its message. When I find that message distasteful, I consider it bad architecture.
