Slender columns support the cantilevers in rhythmically placed quartets, giving a feeling of weaving your way through a modern bamboo forest. The striking crown of the building is surrounded by vertical aluminium slats with carved flower patterns, which are reminiscent of the decorative latticed windows in the old town. These slats filter the light and keep the heat out. In the evening, this unique facade is recognizable from afar. The stepped building offers shelter to visitors both inside and outside and creates a smooth transition from exterior and interior.

Below the cantilevers are four sunken patios for outdoor activities, with the largest accessible from the square; lectures, concerts and exhibitions can be organized here. Looking up, you can see the special finish of the awnings: champagne-coloured aluminium panels with a linear staggered relief, providing additional decorative elements to the facades. The rational construction of the library allows maximum flexibility, so that the building is prepared for future changes.Once inside, the double-height atrium is inhabited with a work of art by Paul Cocksedge.

Art is exhibited everywhere in the building, not just to look at but also interactive art to touch and play with. A red sculptural staircase adds an exciting element to the geometric building, intersecting all levels and is visible everywhere through the subtle wooden-slatted flight of stairs. The ground floor is spacious, transparent and warm due to the wood finish. Upon entry, you are greeted by an arrivals area and the welcome desk, a living room is also located here where you can read newspapers and magazines.

The children's library with imaginative bookcases and an adjoining patio under the awning for outdoor play is situated below. This level is also home to a spacious study room with its own entrance, where students can study 24/7. As you make your way to the upper levels of the building, you first encounter a media library along with a library for teenagers with its own lounge. The general collection is located on the level above this. Beyond there is a floor dedicated to the heritage collection including the Tainan Memorial Exhibition, Japanese Collection Archive and books by Taiwanese authors.

There are also four outdoor areas situated here, which are arranged as roof gardens, as well as three multifunctional spaces for classrooms/workshops and a cafe. At the top of the building, you will find the theatre and conference hall. From the uppermost levels of the building, a beautiful view of the city through the vertical slats is on display. Furthermore, the building has an art gallery, a maker space and Braille library.
