This is a subject which has not been thoroughly masticated by the Mudcat. I thought I'd give it a try.   It is said that "Form Follows Function" and I believe that to be true and self-evident. But I also believe there is a point where the desired functional objectives have been achieved and secondary and tertiary goals are added to the structure(s) and an evolution of form continues to progress, telling us something about ourselves and our beliefs.

The need for shelter can be met with an easy simplicity. A lean-to, a snow hut, a grass shack will suffice, depending on the environment. Urban apartments, middle class suburban domicile or a cell in C-Block at the State Pen: each says something about our society, it's values, dreams and aspirations.

Consider the small New England town: what is the largest building? Why? Consider downtown Manhattan: what is the largest building? what WAS the largest building? Why? Why was it the target of the Islamic terrorists? THEY noted what the architecture represented.

Consider the Ancient World, the design and the size of the temples or the halls of government. Why did the elders sit in the Gates of the City?

Lest I bloviate, I'll throw it up to you all and see what you think, if your interested. Have fun!
