I have read somewhere that with land so cheap in Houston (relative to NY, LA, Chicago), it is a lot more convenient to build either a campus of smaller buildings or a plaza of shorter buildings, rather than building up higher. Skyscrapers are very inefficient in design with just about every regard other than the land they occupy (and of course other than making the city look badass). It makes economic sense to build up in those other cities because land is so expensive, but Houston is a different story.
I can't remember where I read this, but I will try to locate a source.
Unfortunately that can mean the end to super tall buildings in Houston
. April 4, please prove me wrong!
