A great spreading oak tree is the centerpiece of the urban lodge-style commons area of this hall. The tree trunk shows a cross section of growth rings in terrazzo, alternating with water-jet cut Kempas marble, a rich golden-red stone with a striated, wood-grain pattern. Over 800 hand-set pieces of Emperador Dark marble in palladiana terrazzo depict the bark of the tree branches. The emblematic fish from early Christian art and other images in water-jet cut aluminum or stone, with aggregates of mother-of-pearl and metal shavings, are expertly incorporated in the walkway to reflect the heart and legacy of the college.
