There are justifications for the multifunctioning room as well as the multifunctioning building. A room can have many functions at the same time or at different times. Kahn prefers the gallery because it is directional and nondirectional, a corridor and room at once. And he recognizes the changing complexities of specific functions by differentiating rooms in a general way through a hierarchy of size and
quality, calling them servant and major spaces, directional and nondirectional spaces, and other designations more generic than specific. As in his project for the Trenton Community Center, these spaces end by paralleling in a more complex way the pre-eighteenth century configurations
of rooms en suite. The idea of corridors and rooms each with a single function for convenience originated in the eighteenth century. Is not Modern architecture's characteristic
separation and specialization of program functions within the building through built-in furniture an extreme manifestation of this idea? Kahn by implication questions such rigid specialization and limited functionalism. In thiscontext, "form evokes function."
