Commercial complex, that is defined as an active and dynamic complex in the form of a space within the city, can meet the needs of citizens in a desirable way. It will be wider in urban and even metropolitan areas, it will be a project with special service features. One of the methods of sustainable development is the use of techniques adapted by nature. Contemporary man, in particular, is always striving to know and apply nature in order to know it. Conscious imitation in the current situation in the form of a case study of solutions in nature, means to achieve a database of successful solutions that will solve the problems facing humans today and its needs (especially in the field of architecture). The purpose of explaining the architectural design of a commercial complex based on bionic structure inspired by the starfish structure and inspired by the bionic structure is to discover a correct architectural structure in commercial spaces. The main question of the research is how to structure the existing bionic structure Use the starfish in the design?
