I just came across an interesting article by Thomas Schielke, a writer of a monthly column about light and space – light matters. Schielke is a co-author of the book Light Perspectives. In his post he presents his ideas regarding the issue of whether shadows give form to architecture. He used Leonardo da Vinci’s and Louis Kahn’s ideas to present the role of shadows in architecture.
According to da Vinci, there are three types of shadows. These are attached, shading, and cast shadow. Kahn considers these type of shadows in his architectural designs along with the idea that light is the giver of all presences. There can be no shadow without light so his creations doesn’t have pure dark places. A dark place must have enough light to differentiate darkness and light.
When designing a building, it’s important to have harmony between light and shadow. The form of an architecture is defined by its structure and its natural light’s character. When playing with shadows, it’s all about balance to create a mysterious space.
