First, the scale is close to the people

The scale of commercial street should be based on the activities of pedestrians, not on the vehicles passing at high speed. The vertical range of shoppers' attention is mainly concentrated on the first floor of the building. It is almost "turning a blind eye" to the scope of more than one floor. The horizontal attention range is generally between 10 and 20 meters, while in a commercial street with a width of more than 20 meters, pedestrians are likely to only pay attention to the shops on one side of the street and will not advance within a width of more than 20 meters. This just shows that the focus of commercial street architectural design should be placed on the third level of architectural design.

Second, the definition of space

The space of people's activities and perception in the commercial street is three-dimensional. Therefore, designers should design streets in length, width and height. First of all, the length of the commercial street depends on the scale of the business, and there is no certain law. However, according to the psychological feeling mode, outdoor architectural space can be divided into centripetal, cohesive, so-called "positive space" and divergent, acceptable and difficult to aggregate popularity "negative space". As a commercial street, there is a demand for aggregation. It is necessary for pedestrians to stop and feel the viewing environment when shopping and resting. It must be a "positive space" shaped by architectural means. In other words, some form of space markers and limiters are needed at both ends of the commercial street to mark the beginning and end of the commercial street. At the same time, it also serves the purpose of isolating the garage traffic space from the shopping space.

For example, in the commercial street design of Beijing Pearl River International City, an archway with a combination of Chinese and western styles is set at one end of the entrance as a sign, which not only makes the entrance more eye-catching and attractive, but also acts as a barrier to separate urban traffic and pedestrian space. At one end of the community center, a towering bell tower ends as a commercial street, marking the center of the community. The establishment of signs at both ends has established a wide range of commercial streets, and shoppers can feel their position in this space at any time and predict the distance they have not walked. This technique avoids the confusion and loss that shoppers often feel in big markets.

Third, the diversification of styles and colors.

The attraction of the naturally formed traditional commercial street lies in that it was built in different periods, and different styles of pavements were mixed together, forming extremely diverse and unified prosperity. Newly designed commercial streets are often monotonous because of artificial unity. In order to pursue the artistic conception of traditional commercial streets, designers should consciously give up the pursuit of simple and unified opposites, and even deliberately create shops with various styles.

Different styles of building units are put together to remind people of the customs of small towns. Even for different units of the same design, the difference in appearance is enhanced by the change of materials and colors. The charm of commercial street lies in the diversity of facade forms. This is also the difference between a commercial street and a large department store.

4. Softening and refining of flour raw materials

The important difference between the appearance of commercial street building and other buildings is that the store owner needs to carry out secondary decoration on the appearance of the store according to the nature and characteristics of its own operation. The exterior design of the building is only a basic platform. Shops need to install signboards at least, and some chain stores need to change to specific colors and styles. Signboards, advertisements, light boxes and other outdoor decorations often become the most striking elements in the architectural appearance. Out-of-control secondary exterior decoration may conflict with the original architectural design and even destroy the effect of architectural space. Therefore, the appearance design of mature shops should consider the possibility of transforming external decoration, and reserve the location of shop names, signs, advertisements and other decorations.

Fifth, pay attention to non-architectural elements.

The formation of outdoor space and atmosphere of commercial street mainly depends on the spatial form and elevation form of the building, and also depends on the use of other architectural elements, such as outdoor dining places, pavilions and other functional facilities, flower stands, fountains, sculptures, lamps, signs, telephone booths and other equipment, lanterns, antiques, props and other decorations, floor coverings, tiles, railings and other surface materials. These elements are the interface between commercial street and people. In order to make this interface more "friendly", it is necessary to deepen the design of commercial street from the perspective of landscape and garden.
