In the design of dining space, the common spatial combination forms are centralized, group and line, or their comprehensive variants. Centralized space combination is a stable centripetal catering space combination, which consists of a certain number of secondary spaces around a large dominant space. This center is generally in regular form, such as circle, square, triangle, regular polygon and so on. The surrounding secondary space is generally made into different forms and sizes, which makes the space diversified. Its functions can also be different, and designers can flexibly organize around the central space according to the shape of the site, environmental needs and the respective functional characteristics of the secondary space. Group-type space combination connects several spaces closely, or makes several spaces closely connected by a certain space axis. In the design of dining space, group combination is also a common form of space combination, and it is more common that several dining spaces are closely connected to each other to form a group combination. You can also combine several dining spaces along a passage that passes through the group. The passage can be straight, broken or circular. In addition, several small dining spaces can also be arranged around a large dining space. This kind of space is similar to centralized space, but compared with it, this kind of plane combination is more free and flexible.
