Design choices are important when building an arena for a city, and they depend upon several factors. The types of events they will host are just as important as the size of the lot they will be built on. Local streets will be used for the crowds to assemble, but public transportation networks are another factor that will help make the design choices. All of these will be combined, and the builders will attempt to make it easy to get in and out of the arena while creating enough space for many different types of events.
Sports arenas used to be segregated from those used for cultural events, but many civic groups have found that combining them is possible. Weather might play a role in their choices, but even the biggest buildings can now have roofs. Modern technology has made it possible for them to remain a closed building, but the roof can be withdrawn on many larger buildings to create an outside venue during good weather.
Cultural events used to be much smaller than they are today, but modern entertainers often perform before thousands of fans. It has become a way to draw popular figures to smaller cities, and the crowds will have plenty of room for their friends and family to enjoy it with them. Using a large building to host cultural events has helped make it fiscally feasible to build larger areas, and there is little worry that the building will stand empty for much of the year.
While the design choices will have many contributing factors, most of them will be based on housing the largest audiences possible for any event. Their central area will be created to be changed for different events, but the seating surrounding it will remain largely unchanged. The contractor building the facility will be able to create a venue that will give the city the most value for their money, and modern technology will help them build a space that will be viable for many years to come.
