SkyscraperPage.com also features unique skyscraper diagrams, a database of construction activity, and publishes popular skyscraper posters.
UofP Stadium definitely looks nice, but it kind of sits out in Glendale with nothing around it (although that's changing) and looks kind of ominous and imposing from the freeway out there by itself (er...next to Jobbing.com Arena, home of the Coyotes).
I've got a plan for a new Detroit Red Wings Arena at my website. Its based upon the Old Olympia Stadium. The site has some pretty cool drawings and floorplans, though they're amateur and not quite as polished as some of the other drawings at this site. Chcek it out at http://www.newolympia.blogspot.com
I would post some pictures, but they just come up as red X's.
