The article is devoted to the development of modular construction in Russia and related problems. Given the ongoing shortage of living space and the need to modernize the housing stock, modular construction is a promising solution for the rapid construction of affordable housing. Despite the advantages such as faster implementation times, high flexibility and adaptability to various needs, and the ability to quickly dismantle and expand buildings, the technology faces serious challenges in Russia. The lack of a unified regulatory framework and certification brings additional difficulties with financing and lack of infrastructure, which significantly limits the mass use of modular structures. These factors slow down the process of integrating modular construction into domestic construction practice. At the same time, international experience and successful examples of the implementation of such projects, such as the Habitat 67 residential complex in Canada and the high-rise building "Naikagin Capsule Tower" in Japan, demonstrate the possibilities of modular construction in various sectors. Russia continues to actively work on the adaptation of modular technologies, which opens up prospects for solving housing problems and the rapid construction of social facilities. In the country modular construction can play an important role in solving housing problems, especially in regions where traditional construction methods are economically impractical. Despite the existing problems, the implementation of this technology continues to evolve, which opens up prospects for future growth and improvement of the construction industry in Russia.

The article outlines modern trends in the formation of the architecture of concert halls based on the use of long-span structures in the structure of the facility. The parameters of concert halls, which are affected by the use of long-span structures, are considered. Examples of the implementation of the architecture of concert halls using long-span structures made of various materials are presented. Theoretical assumptions have been made about the division of long-span structures into two types according to the nature of their influence on acoustics.

The article presents a comparative analysis of various types of long-span structures used in covering concert halls. Their influence on the acoustic characteristics of the concert hall box is considered. Examples of the implementation of the architecture of concert halls using long-span structures made of various materials are presented. Conclusions are drawn about the division of large-span structures into two functional groups according to the nature of their influence on acoustics with the corresponding option for space-planning solutions for concert halls.
