Theater architecture is a widely recognized engineering project in the construction industry with strong professionalism, high technical complexity, and a wide range of specialties involved. Theater architecture is a systematic project that coordinates more than two dozen specialties, including architecture, architectural acoustics, lighting, sound, stage machinery, stage aesthetics, intelligent control, artificial climate, and decoration engineering. Any errors or inadequate cooperation in any link can affect the operation of the system, Ultimately affecting the architectural and performance effects. Firstly, it is important to select the design unit for the theater construction project. The theater construction project, due to its involvement in multiple specialties, complex structure, and high technological content, can be said to be a difficult building in the construction of civil public buildings. The overall strength of the design unit is strong, and the main creators have experience in designing large modern theaters. This is a prerequisite for the owner to select them for the design bidding, which is one of them. Secondly, innovation is the soul of good theater design. Owners should encourage innovation when submitting design requirements, and creators should be bold in their designs, fully absorbing the achievements of today's economic, social, and scientific and technological development. Secondly, the repeated modifications after the scheme design is determined are an important part of enriching and improving its design. Due to various reasons, most winning bid proposals are not perfect. The owner needs to make design modifications based on their own investment, project functional positioning, project environment, local planning, fire department requirements, etc., absorb the advantages of other bidding proposals as much as possible, seek the opinions of experts from all aspects, and do this work well to lay a foundation for subsequent design. Once again, it is important to ensure that all professional designs are entered in advance. Generally speaking, professional design should precede architectural design. Specifically, it includes: architectural acoustics (which should be implemented throughout the entire design and construction process), stage machinery, stage lighting, stage sound, air conditioning systems, environmental protection and energy conservation, fire protection, traffic planning, etc. But in the actual operation process, a lot of these tasks are only started after having a design plan and determining the architectural design unit. It is worth noting that with the development of science and technology and the progress of society, the requirements for stage art are also getting higher and higher. Various professional technologies are changing rapidly, and they are also becoming more specialized, modern, and scientific. Product updates and conceptual updates are fast. Many of the professional designs mentioned above cannot be completed by the architectural design department, which requires the owner to determine these professional designs through separate bidding or commissioned design, and integrate them with the architectural design as soon as possible to become a complete theater construction project design. The functional positioning of theater construction is an important issue that owners need to determine in advance when deciding on theater construction. The functional positioning mainly includes: firstly, the construction scale. Such as total construction area, number of audience seats, etc., among which the number of audience seats is an important indicator. The current theater regulations in our country divide the scale of theater buildings into four types based on the number of audience seats. Different types of theaters have different technical requirements, functional positioning, and investment needs. The second is whether the theater is comprehensive or professional. Among them, there are complex and comprehensive theaters that mainly focus on song and dance performances, theatrical performances, and theatrical performances. And professional theaters are relatively simple, often to meet the needs of
