Civic centers used to be built with cultural events in mind, and they were often smaller than those used for sports competitions. It can still be true for some of the cultural events that will be hosted locally, so many new arenas are built with several different buildings attached to them. Office space for administration is also an important feature, and it is generally housed somewhere on the property. Builders will accommodate as many spaces as possible in a single building, but they are more than willing to create several smaller attached facilities if necessary.
For those cities that would rather have combination venues, their choices are almost endless. Some of the buildings will be flexible, and they can be easily combined with other buildings on the property to create a larger space for a special event. The beauty of designing this type of entertainment complex is that several very different events can all be hosted at the same time.
