There's the anti-edifice complex company - Intel. Intel built their own office buildings to their own design, which was to have acre-sized floors with bullpens.[1] Grey bullpens. Grey walls. Grey carpet. It's depressing just to visit. I'd hate to work there.
Apple's new mothership[2] definitely indicates an edifice complex. It could work out, though. Apple is currently spread over a large number of modest buildings separated by busy roads. The mothership is a big round building with a lot of underground parking. Just getting most of their people within walking distance will be a win. Of course, that assumes Apple allows them to talk to each other.
The city of Mountain View insisted that Google put 5,000 housing units into their plan. That should help.
The classic edifice in Silicon Valley is IBM Almaden Research, from the 1960s. You enter through a modest gate and drive through rolling hills for a mile, until you reach the big glass and steel complex atop the mountain. The cafeteria looks out on miles of unblemished parkland. A lot of good stuff came out of there, including three Nobel prizes. Today, it's a shadow of what it once was. Part of it is rented out.
Overdoing this sort of thing is rare in the US today. Moscow, Dubai, and Beijing, though...
