Before we peek inside, a few words need to be said about the green bricks. Some Penn officials feared they were a radical choice that would ruin the effort to brand the university as an oasis of tradition, but the school's dean, Eduardo O. Glandt, insisted that a building devoted to bioengineering had to look modern. Because the field is freighted with difficult moral issues, Williams and Tsien understood Skirkanich had to present its modernism with a human face.They used McMansion brick and still went over budget by $23 million? Yikes.
So, while the bricks are a synthetic, Prada-esque green, they're also handmade. Ordinary red clay was pressed into molds that left the bricks puckered and rough. After that, they were coated with a manganese glaze. To ensure the custom product would stand up to time, the architects had them tested twice. Then the bricks were laid by hand, one by one. Compare that process with the Kimmel Center's, where factory sections of prelaid brick were wallpapered onto the exterior. [emphasis added]
