Restored Second Floor East Corridor, Looking Towards the Earl Center for Teen Learning & Leadership Entry - Inset construction photo shows removal of plaster vaulted ceiling for installation of new MEP and life safety systems. New decorative painting replicates the historic motifs, and terrazzo floor, marble walls, and plaster walls are now repaired and restored. A new steel and glass entry to the Teen Center provides both security and a strong visual connection to the corridor’s steel framed windows overlooking the Central Hall atrium.
