In the process of China's economic development from crude to intensive transformation, complex buildings play an increasingly important role. Among them, the commercial office complex functional system for commercial, office, exhibition and conference, catering and parking and other functions of the aggregate, a variety of functions as if the ecosphere of the environmental system, reflecting a kind of interdependence to help the dynamic relationship, so as to form a multi-functional, high-efficiency complex and unified organism.
This case is located in the future business center area of Guangzhou - Nansha Economic and Technological Development Zone, adjacent to the Prayer for the blessing of the hotel and the Local Taxation Bureau, surrounded by larger commercial office buildings, its own scale is relatively small, the plot area of 15,129m2, with a total floor area of 45,387m2; on the other hand, the area has not yet formed a mature commercial atmosphere. On the other hand, the area has not yet formed a mature business atmosphere, it is difficult to attract enough popularity in the short term, if the continuation of the general mass commercial office business model, with a small store focused on the ordinary form of shopping malls and small office space office building is bound to lack sufficient competitiveness. Therefore, in the early stage of the design of this case, the designer and the party tried another way of thinking: the commercial office complex services targeting specific higher income groups. Usually this kind of consumers in the shopping before the purchase of a clear location, and will choose some goods complete high-grade shopping malls as a fixed place to shop, in addition to consider the variety of shopping, and more enjoy the high-grade shopping malls to provide quality service and good shopping environment. Therefore, the podium part of this case will be positioned as a luxury shopping mall, mainly focusing on luxury goods, supplemented by food and leisure activities; while the tower part is positioned as a high-end business office building, mainly providing large space for corporate offices. So how to reflect the architectural environment, fa?ade modeling and internal space of the high standards and sense of the times, while taking into account the economic benefits, has become the primary foothold of the program.
1Architectural texture and urban texture
Considering the daily management of the building and its phased construction, the commercial podium is arranged at the north end of the base near the city's main road into the harbor, and the office tower is arranged to the south of the podium, with the structures separated and independent of each other, and with only two floors of connected corridors as the linkage body. The main entrance of the office tower is placed on the north side, opposite to the main entrance of the commercial podium, which provides convenient access for office workers. Between the tower and the podium to form a street and commercial entrance plaza, as the main entrance and traffic distribution plaza, and at the same time with the south side of the podium by the riding tower and subtropical plants composed of green belt to form a landscape axis. The main entrance of the podium is located in the southeast, facing the entrance plaza; while another sub-entrance is located in the west, combined with a small green plaza at the entrance, mainly to provide the west side of the Prayer for the blessing of the hotel's pedestrian flow into.
In the spirit of accessibility, safety and convenience of the traffic organization principles, this case will be the main entrance of the car traffic on the west side of the city's secondary arterial Jinsha Road, 70m from the intersection of the city's main arterial into the port Avenue, and the other two secondary entrances are located in the northwest end of the base and the southeast end of the base. A pedestrian-vehicle separation system is set up, with the vehicular traffic forming a ring road around the tower and sufficient parking spaces and underground garage entrances and exits along the road, and the ring road is also used as a fire escape. The main entrance for pedestrians is placed north of the main entrance for vehicles, connected to the entrance plaza, and adjacent to the two main entrances of the complex, leading directly to the commercial street and subtropical green belt. Solve the base of the road system and the public **** space relationship between the second degree of human space problems, so that the base of the small environment for the city space open, architectural texture and urban texture of mutual penetration, will be better adapted to the building and integrated into the city's spatial system.
2 Architectural Plan Design
Office Tower: The tower part is designed as 16 floors above ground and 2 floors underground. The 1st and 2nd floors are the catering area, the 3rd to 16th floors are the business office area, and the underground floor is the garage, with a total height of 59.8 m. The vertical transportation core is arranged in the middle of the plane in the west position, and it leaves a larger and more regular office space as much as possible under the principle of meeting the evacuation distance. On the west side of the plane, sky gardens are arranged every 4 floors, and combined with the design of landscape balconies, the ecological landscape is integrated into the building to create a comfortable and pleasant office environment. At the same time, from the point of view of energy saving, it solves the problem of long sunshine time on the west fa?ade and low utilization rate of the building space. The north end of the third and fourth floor plan is connected with the podium part in the way of corridor, as a link between the tower and the podium, so that the two are organically linked together in space, which is integrated and full of changes.
Commercial podium: the entrance plaza is designed on the southeast side of the podium, where people from different directions meet and disperse, and then diverge in an orderly manner, and the commercial street formed between the podium and the tower also effectively distinguishes the commercial and office traffic. Architecture is the continuation of urban culture, Guangzhou's "riding" is a major feature of local architecture, this case will be the south of the commercial podium is partially designed as a riding tower, convergence of commercial popularity, weakening the sense of closure of the inner street, to create a friendly and pleasant flow of space. The atrium in the shopping mall is designed as an inner street, and partially enlarged to arrange a rest area for the convenience of accompanying shopping men waiting for a rest, injecting new vitality into the space of modern commercial buildings, and also an important place to create a chic commercial atmosphere. By the atrium to form a ring road shopping flow, creating more shopping opportunities, the end of the arrangement of beauty salons, coffee bars and other spaces that can make people stay, to avoid the emergence of commercial dead ends, the formation of a pleasurable, gorgeous shopping atmosphere.
3Skin and volume
The architectural design of the entire commercial office complex focuses on modernity and fashion, and pays attention to the detailed drawing of the skin in an attempt to express the unconventional and extraordinary style of high-end commercial office complex, forming an elegant, rich, three-dimensional and versatile dynamic organic whole of the city.
Office Tower:
A. Due to the 60m height limitation, in order to visually elevate the tower, the tower is designed as a double building occluding each other, and through the triangular frame on the roof to enhance the sense of perspective of the tower, so that the building's modern and rich skyline is shown to the city as much as possible, and simulate a single-slope roof in order to respond to the overall planning requirements of the Nansha area.
B. The double building forms the contrast between reality and reality through the change of volume and material: the west side of the tower is taller, and the fa?ade is mainly hidden frame glass curtain wall with white color and lower transparency, mainly vertical strip composition, while the west fa?ade is the white solid wall with the same vertical strip composition, and the subtle concave-convex change is added to make the light and shadow change of the solid wall surface more abundant under the sunshine; the east side of the tower is relatively shorter, and the fa?ade is mainly bright frame, so as to show the modern and rich skyline as possible. The eastern part of the tower is relatively shorter, and the fa?ade is mainly an open-frame glass curtain wall with dark gray metal frames, high glass transparency, and mainly horizontal strip composition.
Commercial podium:
A. The fa?ade is epidermalized and transparent, through the detailed division of the glass curtain wall and the matching of the material and color, it creates coordinated and changing visual characteristics, which makes the building itself more attractive and stimulates people's desire to consume at the same time.
B. The use of the top of the building nearly two-storey high red frame to enhance the sense of volume of the podium, and simulate the common Nansha sloped roof, the vertical part of the installation of billboards, retaining the integrity of the building fa?ade, which can increase the visibility, but also shows the high-end commercial buildings and other buildings with a different fine and stylish.
4 Conclusion
Since this case is located in the new development zone, taking into account the market demand and effect, the designer boldly adopted another way of thinking, breaking the previous design of many commercial office buildings: to determine the specific consumer objects, and then the form and style of the building for the positioning of the commercial and office as both independent and linked to the consideration of the complex, and the introduction of the concept of the commercial street. It also introduces the concept of commercial inner street, sets the main entrance of the building on the secondary road of the city, and creates a noble and comfortable commercial office environment. The completion of the commercial office complex as an urban organism will also drive the synchronized self-renewal of the area in which it is located, with the effect of improving and perfecting the value of the urban area and driving the development of the surrounding industries. The enterprises and people gathered here will also become an intangible asset of the region and play a strong radiation effect on the development of the region.
