The Polk-Wisdom Branch Library has served the citizens of South Dallas since 1970. The existing building was originally programmed as a library and bomb shelter, resulting in a building with limited natural light. Security being an issue based on the original location of the entry formulated a need for reorientation of access and pedestrian safety.
With limited site constraints, the design solution internalized the transformation, focusing on flexibility and organization of spaces over increased size. A dynamic glass box expansion with random shapes 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 the natural light that filters into the space from new glazing. Random shapes of colored glass are repeated along the north façade providing an artistic and colorful backdrop for daily patron activity. The same angular layout found in the glass is repeated in the layout of stacks, which define the various user areas, while providing consistency to this library which makes it "feel" much larger.
The library staff expressed the need for ultimate flexibility as part of the program requirements. To maximize flexibility no permanent walls were used within the main library area, allowing a total reconfiguration of use by simply moving furniture. The design team specifically designed a system of mobile study rooms, mobile storytime panels, and mobile staff work stations to meet the need of the flexible and changing environment that libraries are facing today and in their future. 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 have variable height adjustment, allowing staff members to sit or stand depending upon the task required.
Sustainable principles were incorporated throughout the design and it is currently pending LEED Gold certification. Some of the green features include; an improved thermal building envelope; a geothermal system that will utilize the constant ground temperature to heat and cool the facility; the use of locally manufactured materials; water efficient fixtures and irrigation; diverting over 80% of the construction waste from the landfill.
The resulting design solution is a compact 16,800 square foot branch library that transformed an outdated brutal box, into dynamic flexible platform for library service and public use.
