“Architecture is not about form, it is about many other things,” he said. “The light and the use, and the structure, and the shadow, the smell and so on. I think form is the easiest to control, it can be done at the end.” Zumthor, who is best known for designing material-led projects such as the Therme Vals thermal baths in Switzerland and the Kunsthaus Bregenz gallery in Austria, told an audience that his ultimate goal is to “create emotional space”.
I strongly agree with his opinion. Like what his status shows, the material is one of the most important part of architecture which can control many aspects of architecture such as the light. When light spreads on the rough surface, the condition of reflection would be even. So the light in this condition would be soft and warm. In contrast, if the light spreads on a smooth surface, the light would be reflected directly and make the room extremely light. Therefore, the using of material is very important to the light condition in architecture.
For example, when an architect design a library or museum in which people need a quiet circumstance, he would choose the material with rough surface for the interior of the building. When the reflection evenly spread to different directions, the light would be soft and dim. As we know, the soft light could calm people down and make a peaceful feeling.
And with the same theory, for the market or business building, the surface of the material would be smooth. The directive reflection can make the room bright and people could see the things clearly. The luminous circumstance could improve the efficiency of people.
