Daegu Gosan Public Library

Flexibility for updating book collections is one fundamental idea of the contemporary library, and our ambition is to apply this concept to the building facade, creating an urban scale bookshelf collecting and presenting the images, memories and social events of the local community and the city. Each of the west and east building facades is equipped with five 10x10m installation panels. Working like the Pin Art (or Pinscreen), each panel consists of 40x40 movable pins in small holes. The pins, being able to slide back and forth by a computer controlled motor, can cast different shadows like a relief sculpture. The pinscreen panels can work independently or jointly, showing or reacting to different public topics.
The geometry of the building is developed from the specific site conditions and urban context. Extracted from the site boundary, four axes have been used to shape the general configuration of the building. By carefully doing a tree survey, the new library building tries to use the empty ground and minimizes its influence on the existing trees. The public access is another key consideration of the design. The original footpath across the site has been kept in the new proposal by splitting the ground floor into two parts. A lifted platform is introduced to create a new outdoor public space replacing the existing park used by local residents for recreation.
To integrate local activities into traditional library services, four spatial compartments are architecturally defined for specific duties. The common area space is at the north part of the ground floor, facilitating library book circulation by integrating reception, book checkout/return, information search, and librarian-patron interaction all together. The office and maintenance space is located at the south part of the ground floor and the basement. It provides employees a separated space but also a good connection to the other compartments. The culture and lifelong education space is on the first floor, and a large open plan with portable walls are used to adapt to complex local activities. The second and third floors are open user space providing open-shelf, reading space and digital data. The accesses to all the four compartments are logically organized to avoid disturbance.
