Flexibility is now paramount. There is the need for teaming as well as private, conference, train, and collaborative in the same space. Architecture should make a statement about sound, sight, and feel. It should call one to an experience. It should say theater.
Chancels are wide open with little bolted down, lobbies are much larger, more parking.
Multipurpose rooms are used more for worship now. Education space is now designed to house week day child care. The immediate needs are often sacrificed for the long term needs. Many people are beginning to think of architecture as a form of entertainment, like sports bars or Planet Hollywood. For instance the Fremont Street Experience, a covered promenade that revitalized downtown Las Vegas.
