The library serves as both a place for the individual act of reading and for the communal act of gathering. Separated into two volumes, the Library with Two Faces seeks to address this dichotomy. To create the individual spaces, located in the lower volume facing the surrounding communities, and the group spaces, located in the higher volume facing the city, a module was designed to operate as both object and organizational system for the building. This wooden module aggregates to form a variety of programmatic spaces and, ultimately, comprises the entire building, from furniture to structure to facade. Designed at the moments of inhabitation created by a construction detail, the Library with Two Faces is an exploration in modularity, construction, and the use of the library.
