Guangzhou Baiyun Railway Station TOD, China

Guangzhou Baiyun Station is a high-speed rail TOD (Transit-Oriented Development) and the only one of its kind in the world at the time of design. Comprising a station of 11 platforms and 24 tracks, six subway lines, and three bus terminals, this enormous transportation hub is expected to have an estimated daily user base of 360,000 people. The development area above the station is approximately 170,000m2, and the surrounding area, including offices, commercial facilities, Serviced Apartments, and housing, has been developed as an integrated whole, covering an area of approximately 500,000m2.

It focuses on the efficient use of land in the urban area and the creation of a sustainable transportation system centered on public use. The most significant features of the development are the Transit Loop, the Grand Canopy, and the Station Core. A three-dimensional ring-shaped pedestrian space, "the Transit Loop", has a height difference of five stories from the second basement to the third floor. It splits into two, following arcs on both sides and connecting to another subway hall approximately 400 meters away. It is a place for relaxation and recreation not only for station visitors but also for local people to spend their time.

The 30-meter Grand Canopy is inspired by Guangzhou's symbolic cotton flower. Station visitors use it as a plaza, promenade, playground, and running track. The structure that supports the petals is realized by combining two steel columns that follow the outline of the petals. Considering the load restriction, a PTFE membrane was adopted to reduce the weight of the petals, realizing a seamless "cotton flower" facade.

The Station Core is an open atrium Stretching from north to south and captures the sunlight from different directions depending on the time of the day. Louvers with three different angles were placed along the arched beams to capture the optimal amount of light. Fine-pitched collar beams installed between the arch beams act as solar shading louvers. Elegant, symmetrically curved columns are expressed on the inside of the large cantilever of the Grand Canopy station facade that counteract the force acting on the outside and maintain structural stability.
