Regeneration Project of Shougang Oxygen Factory Southern Area

Shougang Park is the largest industrial site in Beijing, and the "memory of the times" of a generation. In 2016, the Organizing Committee of the Winter Olympic Games settled in the park, which has enabled the Shougang Park to regain vitality. Located in the south of the Big Air Shougang, the project is adjacent to Chang 'an Avenue, near the Yongding River, and facing Shougang's core "No.3 Blast Furnace" across the bank, enjoying unique landscape resources and geographical advantages. The plot involves a reserved 16,000㎡ oxygen production workshop, the #3350 workshop, a new-built performing arts center, and office & business complex along the lake. As for oxygen production workshop renovation, architects keep the most distinctive parts of the structure, the roof load is still carried by the original structure, while the newly added second and third floor slabs and structural columns form a new steel framework system. The original factory building will be used as a corporate exhibition center, with a three-story glass volume inserted diagonally as the foyer. The exterior wall is made of grey metal plates, which presents a low-profile attitude among the architectural complex. The Tencent Performing Arts Center involves building expansion and the renovation of #3350 workshop. Architects keep the basic structure of old workshop, and some trusses are intentionally exposed. Part of outer walls are removed and glass material is added to meet the indoor lighting requirements. The interior is built into four floors according to the height, and the entrance hall presents the full-height space. The middle part of #3350 workshop is opened, and exposed roof trusses and outer corridor on the second floor enclose a small outdoor theater. The workshop will be used as accessory occupancy and office space of the Performing Arts Center after renovation. Based on the technique of "homogeny" and "repetition", the extended volume of Performing Arts Center continues 6m modulus steel truss structure of old plant building. The large, medium and small studios are placed in the steel structure space, and three concrete boxes contrast with the metal framework to bring rich light and shadow changes. On the west side, the combination of round concrete walls and square glass boxes enriches the overall shape. The outer porch space on the second floor provides a resting platform for visitors to enjoy the Yongding River and maintains view. The new office complex on the north side consists of a 2-storey catering building and two 6-storey office buildings with excellent views. The two building materials, concrete and glass, harmoniously integrate with the old building on the south side. The "eave" element is introduced into the facade vocabulary, the horizontal eaves are the extension of the horizontal lines, which can stretch the sight line and enable people to view the scenery under the eaves. Meanwhile, large areas of glass introduce lake and mountain views into the building. The drainage chains are obscured by the staggered screen curtains to further enrich the facade details.
