The general layout of commercial complex buildings is relatively simple. Generally speaking, on the basis of meeting the building concession, coverage and floor area ratio, the single building is placed in the center of the site, and sufficient fire ring roads and fire fighting sites are reserved around it. By analyzing the source and primary and secondary relationship of people flow, the layout of automobile flow lines, people flow and freight flow lines is determined, and the main building entrances and exits are determined. The layout principle of the entrance and exit of motor vehicle parking lot and underground garage should try to avoid the commercial surface along the street, avoid the influence of unfavorable factors on the commercial display surface, and strive to achieve the separation of people and vehicles. The site design should take into account the needs of commercial activities, and a large area of complete outdoor space should be arranged outside the main entrance of the business. The commercial exhibition surface facing the main urban roads should avoid the obstruction of the building by car ramps, outdoor shafts and landscape trees, so as to increase the commercial atmosphere and arouse customers' desire to shop.

commercial moving line design

moving line refers to the route formed by connecting the points where people move in the building. Simply speaking, the business line refers to the trajectory of customers' activities in the mall. Reasonable business line design can guide customers to find a convenient and clear route in the complex commercial space, so that customers can stay in the commercial body for a longer time and pass through more effective areas, while reducing their physical consumption and maintaining their excitement and shopping desire. Moving lines are divided into plane moving lines and vertical moving lines. Plane moving lines seem to be various and varied, but in general, they can be summarized as "I-shaped" moving lines, circular moving lines, dendritic moving lines and so on. There are many varieties of these types, such as "L shape", "8 shape" and "central radial shape", etc. The choice of moving line can be determined according to the plane shape and the area of single layer. The simplest and most effective one is the "I-shaped" moving line, which is mainly suitable for long and narrow planes. This kind of moving line has high efficiency and can obtain the largest number of exhibition surfaces along the street. The disadvantage is that the route is too long and the space is single, which is easy to cause boredom. Therefore, different spatial interest points should be designed according to the length of the route to increase the motivation of customers. The circular moving line is generally suitable for commercial projects with large single-story area and square plane. The circular moving line needs to be connected in series with more commercial contents. Because of the long circuitous route, it is easy to lose the sense of direction in the process of traveling, and there is a situation of "leakage". Branch-shaped moving line is a branch line derived from the active line to extend the commercial path to more areas when the linear and circular moving lines can't radiate completely. This kind of moving line has poor circuitous nature and is prone to dead angle, so it is usually only used when the single-layer area is too large. Vertical moving lines mainly guide people to commercial spaces on different floors through vertical means of transportation such as elevators, escalators and pedestrian ramps. Reasonable setting of sightseeing elevators and escalators can increase the interesting points in commercial spaces and effectively improve the commercial utilization rate of floors. For example, Beijing Chaoyang Joy City is known as the "flying ladder" in Asia, which can directly guide the most popular people from the first floor to the sixth floor. This part of the crowd will adopt a top-down path to solve the problem of high business. The design of commercial dynamic line is very important for bringing commercial space and guiding customers to make diversified consumption. Successful commercial dynamic line design can maximize the rate of return per unit area and bring greater economic benefits to businesses.

Building facade modeling

The single building area of commercial complex is generally more than 51,111 square meters, often exceeding 1,111, 211,111 or even millions of square meters, with huge volume and scale exceeding that of ordinary buildings. Therefore, its facade design has its unique characteristics and needs to follow the following principles. (1) Study the commercial complex from the perspective of urban design, fully consider the relationship between buildings and cities, and properly handle the relationship between building blocks, site concessions and buildings and blocks. (2) There should be an overall modeling concept, unified facade style, uniqueness and uniqueness, and strive to become a landmark building in this area. For example, Vanke Plaza in Jinyu, Beijing adopts the facade design concept of "jewelry box" and wanda plaza in Jinjiang adopts the design concept of "Giftbox", all of which are highly recognizable. (3) The inward-looking commercial function determines that the facade of the building is mainly solid, and modern materials such as large-area stone, aluminum plate and glass curtain wall can be used to highlight the fashion sense of the building. (4) In order to create a business atmosphere, the advertising space should be designed reasonably and orderly, with fewer but better advertisements. The first floor facade should be as transparent and bright as possible, with transparent glass and glass window as the main part. We should give full consideration to the facade effect at night, carry out special lighting design on the opposite side, and combine LED and dynamic advertising to make the building a visual focus in the dark. (5) Emphasize the entrance, with clear priorities. The entrance should be specially treated and differentiated according to its importance. The main entrance should be clearly marked and recognizable.

format architectural design

format can be defined as the form of business, which refers to the specific form of goods and services provided by stores to customers. In layman's terms, it refers to who to sell, what to sell and how to sell. A commercial complex will include a variety of formats, such as main commercial stores, boutiques, supermarkets, restaurants, film and television entertainment, and large-scale complexes will also include hotels, offices, houses and so on. Reasonable business layout and successful investment plan implementation are directly related to the recovery of commercial investment and are the most direct indicators to test the success of the commercial complex. Commercial format design is a complex and comprehensive work, including market positioning, project investment, investment promotion and other work of various departments of Party A and the work of design units. This paper only analyzes it from the perspective of architectural design. Although there are many kinds of business formats, from the perspective of architectural design, they can be roughly divided into three categories: business, catering, film and television entertainment. The commercial part includes main shops, small shops and supermarkets. The division is mainly based on the applicable norms of different formats and the requirements for space and equipment. The reasonable layout of the format can adapt to different format characteristics and market needs, and can simplify the work of equipment specialty and reduce the amount of modification in the later period. Take a medium-sized commercial complex as an example, with an area of about 1 million square meters, four to six floors above ground and two floors underground.
