The Polk-Wisdom Branch Library has served the citizen's of South Dallas since 1970. With no defined entry and limited site constraints, the design solution internalized the transformation, focusing on flexibility and organization of spaces over increased size. . A small glass box expansion with random patterns of colored glass defines the new entry as a "focal point" and begins the reorganization of spaces. A light filled corridor leads patrons through a program room and flexible classroom areas which were recaptured from an existing courtyard. With no opportunity to expand, the main library configuration remains a large rectangle. The existing ceiling was removed to add volume to the space. Painted white with fabric ducts that promote a clean quiet environment, this high volume space reflects natural light that fills the library. Random patterns of colored glass are repeated along the north façade providing an artistic and colorful backdrop for daily patron activity. Angular layouts of stacks define the various user areas, while providing consistency to this library which makes it "feel" much larger. No permanent walls were used within the main library area, allowing a total reconfiguration of use by simply moving furniture. To meet the need of program space while achieving the ultimate in flexibility, mobile study rooms, a mobile storytime, and mobile staff work stations have been utilized. These flexible components are not only mobile but have the ability to change configuration, allowing them to expand for large events and shrink for daily activity. The staff workstations are mobile with height adjustment, allowing staff members to sit or stand depending upon the task required.
