eventually, the physical building will emerge. by that time, however, there will be still another virtual space created by the introduction of electronic media. even after the physical building is completed, its architectural programs may continue to undergo modifications as new media evolve. thus there will be no end to our spatial experiences as the real and virtual spaces overlap in our experience. design in architecture will refer not only to traditional hardware design but also to a more flexible software design that includes programs. we will be designing the time just as we design the space.
