Assembly buildings are structures designed to accommodate large groups of people for various activities such as meetings, events, performances, religious gatherings, or public assemblies. Examples include auditoriums, conference centers, theaters, sports arenas, and places of worship. These buildings require careful planning to ensure safety, comfort, and functionality for occupants.

Constructing assembly buildings involves specialized architectural and engineering considerations, including crowd management, acoustics, lighting, ventilation, and emergency evacuation routes. The design must comply with strict building codes and safety regulations to handle large occupancy loads efficiently.
