I actually wandered around the Pharma building a couple of weeks ago (sorry, I thought that there were already pics of it here!); it's definitely one of the more interesting buildings on a campus that can feel like a collection of mediocre office buildings at times. My impression is that it was designed to be the antithesis to the Life Sciences Building across the street - as shown below, Life Sciences has 2 exceptionally bright, open, airy 5-story atriums decked out in nothing but the brightest, warmest materials. By contrast, the Pharmaceutical Building's main common space on the first 1.5 floors makes extensive use of BLACK surfaces and unpolished concrete, and is much more segmented. Maybe it wasn't intentional, but I thought it was a nice contrast
