I work in a small office park located quite similarly on a grassy field locked entirely by some freeways and other large roads, though the buildings here are cheap and ugly, but even if they weren't, it'd still totally suck. It's isolated, not a part of the city, essentially, it's just a large parking lot (most of which is below the ground, but that doesn't really change anything).
It's quite disappointing. Maybe it's a marvel of architecture, but indeed it's a failure of urbanism (which, I believe, is much more important). It's 2011 and we're still building things while thinking in predefined square lots separated by roads? Such a shame.
