Steven Holl believes that Light is a material. Each project he worked on began with a site and a circumstance, a situation and a program; therefore, architecture should be reinvented for every situation. Architecture should be about place, and the idea that drives the design should be also related to the way the structure, the light, the space, and materials are in some kind of organic relation that ties all these together. However, experiencing architectural space should be free of the idea that drives the design. One doesn’t need to know that in order to get the meaning of the building.
