Since the mid-1920s, the progressive forces of European avant-garde architecture have united on the basis of a common program of functionalism, 77 which was the next stage of development on the path from a superficial simplification of architectural forms to an integrated rationality of architecture. The new generation, brought up on the principles of personal modernity, developed it into a new way of functionalist thinking.
The main thesis of functionalism was the slogan “form follows function”. The requirement for the expediency of a solution, understood not only as an aesthetic problem, but also as a technical, economic, social and cultural one, prevailed over constructive romanticism and artistic expression. The main in the concept of architecture was the requirement of functionality, understood not as something unchanging, constant, but rather as a perspective that needs to be studied, precisely formulated and even created.
The goals of this period included the renewal of the relationship between man and his environment, which aroused theoretical interest in changes in architecture in connection with the reconstruction of the social conditions of society. This social issue led architecture to the need to solve new forms of housing, which became the central motive of the functionalism of the interwar period. At the same time, there was a desire for widespread use of reinforced concrete, new structural systems and materials to create a new architectural morphology. Construction was viewed as a way of organizing life in a biological, social, technical, economic and psychological sense. Functionalism was understood not only as a complex of new functional, constructive and aesthetic principles of architectural creativity, but also as a specific way of thinking.
