The primary design move is to create a occupiable, humble, but simultaneously monumental
roofscape that seamlessly extends the public space of the quad, creating an elevated
commons on top of the original library. Modulation of step height on the roofscape forms
different spaces for study, performances and social events, and roof gardens to collect
rainwater. During winter, when snow covers the roof, it becomes a slope for informal snow
sliding. The roof becomes huge bleachers for festivals and outdoor events in warmer times.
Underneath the roofscape, the original structure remains essentially unchanged. The enclosed
space between the existing roof and the added roof becomes a generous space for reading and
storing books.
