Architecture is a monument of the era.
—— 果戈里 （俄）Гоголь (Russia)
Time is the yardstick of all things and the basic law of architecture. As the carrier of human activities, architecture is also a life like dynamic system. Architecture has the ability to deal with the changing factors that affect the existence and development of architecture, to seek advantages and avoid disadvantages, so as to achieve the purpose of adjusting, adapting and improving human living space and environment.

The function of architecture changes with the change of using subject and time; the space of architecture is polysemy in the perspective of time; the architectural form is displayed in different forms due to the passage of time; the interpretation of architectural meaning varies with time and people. The function, space, form and meaning of architecture constitute the category and value of architectural temporality.

The No.125 factory of China’s military industry, namely AVIC Beijing Shuguang electric machinery factory, is always called “Shuguang factory”. Under the guidance of the general line of “encouraging enthusiasm, striving for the upper reaches and building socialism more quickly, better and more economically”, Shuguang factory was completed in 1959. It is under the jurisdiction of AVIC. It is responsible for the R & D and production of aviation motors (such as the main motors of J-7 III and J-8 II fighters). It was once a military security unit and a solemn and sacred place. Shuguang factory is located at No.5, Jingshun Road, Sanyuanqiao, Dongzhimen, Chaoyang District, Beijing. The main building consists of seven single storey workshops in one line and six horizontal directions, as well as a three storey dormitory building in the East. The building structure is clear and well preserved.

Definition of architecture
As a historical building that played an important role in the military industry in the early days of the people’s Republic of China, Shuguang factory is a relic of the times. In 2019, Shuguang factory has completed its 60th anniversary. As a kind of dynamic system of life, Shuguang factory should not exist only as an industrial building or a historical relic in the process of time flow, and any building should not be simply and rudely defined. The ability of building itself to deal with external influence makes its use function, internal space, external form and architectural meaning change with the change of user and social environment. Therefore, the definition of architecture must take the specific time node as the primary premise.

In the second historical node after the military industrial center, the strong industrial atmosphere and era mark pursued by the contemporary urban people who are tired of high-rise buildings and lattices make Shuguang factory have the basic conditions as a cultural and creative park, while the large space inside the factory reduces the restrictions on the later use of cultural and creative enterprises;The large area of long skylight makes the air convection inside the workshop sufficient and brings sufficient daylighting. In the second Jiazi of Shuguang factory, we define it as a cultural and creative industrial park full of the flavor of the times.

Conversion of functional space
We understand that most of the potential customers in the park are small and micro enterprises or small and medium-sized enterprises, so it is difficult to digest such a huge area. Therefore, we need to divide the plant into several small spaces suitable for use. The main workshop area of Shuguang factory is composed of seven plants. The combined form of one smooth and six horizontal makes its depth up to 108 meters. The super-scale depth makes the accessibility of the inner area a problem, so we put the inner corridor into it to form an inner street. Enrich the form of the inner street, design a courtyard for each household as a buffer area, and set up a shared backyard and external courtyard for two households to provide sharing and rest space for users.

Renewal of architectural form
For the facade of Shuguang factory, we do not intend to make drastic changes, but choose careful minor repairs. Different from the new building, compared with the embodiment of the architect’s personal will, we hope to see the secondary transformation of the building by the user in the long time process. This kind of architectural form updating is more organic and natural.

The uniform composition is slightly broken with the inclined shape along the street surface, which reveals the main entrance while neutralizing the heavy sense of the factory building, and enlivens the entrance atmosphere. The building faces Fenghuang commercial street across the road, near the southwest corner of the entrance and exit of the park. It continues the architectural texture and extends a landmark place for people to rest and communicate, playing the role of Park display.

The facade of the staff dormitory building is well preserved, and the generator can be replaced only by slightly cleaning and replacing the doors and windows. The northeast corner of the site is adjacent to a school. The strong atmosphere of the times can stimulate students’ interest in the past history. The northwest and southwest sides of the building are shuguangli residential area and Shuguang building respectively. On both sides of the building, we have provided a large courtyard for each household. The tenants can manage and use it freely.

Repairing the old as before is actually a respect for the history of Shuguang factory. First of all, we strengthen the original steel-concrete structure and brick enclosure to meet the safety of use. Cancel the windowsill and replace it with French window or door window to improve the flexibility of later use.

Every city has a memory of aging. Since 1959, the No.125 factory has experienced more than half a century of changes. With the development of the city, it has experienced thousands of kinds, from prosperity to decline, from ups and downs to sighs. When the flowers fall, urban areas will also wake up in a new era with a new posture. Fortunately, the 12th Five Year Plan factory will show the strongest historical civilization with fresh urban vitality, meet the new urban era color, and carry the memory of the past time and years, and continue the alternation of the old and the new……
