Exterior spaces were designed as "sculpture courtyards", and are all well connected to interior spaces. Providing for enough natural lighting to ensure adequate interior light levels, while maintaining enough wall space was achieved by elevating the roof of the entrance and allowing clerestory lighting into space, as well as by inserting low-level windows that reflect light off the white floors. The roof structure folds down to the ground at the northeastern corner of the site, in order to create more privacy for the patio area. Soldier course brickwork and the flutes of the corrugated sheeting create interest when juxtaposed with the non-verticality of certain elements of the building.
