Le Corbusier, the greatest architect of the last century, noted that 'architecture is the learned game, correct and magnificent, of forms assembled in light', demonstrating to what extent light has been prioritized in the Western tradition. Tanizaki, on the other hand, spoke of the important of shadows, of extended eaves. Rather than the light that shines directly into a room, he praised the soft light that penetrates a space after being reflected off the floor, and again from the ceiling.
...In Japanese architecture, the gentle light that passes through shoji screens serves a key purpose. It reaches right to the back of the room, so that the space feels bright, even without the aid of artificial light. The soft light filtering through the white film at Takanawa Gateway Station represents a form of light that was forgotten about by Japanese Modernism.
There is an Escher-like quality to these flights of steps, but it is the intricate net of shadows created by the roof structure of this sky-lit sculpture gallery, falling across a succession of vertical planes and reflecting back on the surface of the glass, which commands attention. Slender metal bars set crosswise between the rafters add their own animating rhythm. It all makes for a very complex visual arena in which to view art.
The most serious model shortcoming is that the designer often has a vague, incompletely specified goal, or primary objective. In such cases, the hardest part of design is deciding what to design.
I came to realize that the most useful service I was performing for my client was helping him decide what he really wanted.
Today, we recognize that rapid prototyping is an essential tool for formulating precise requirements. Not only is the design process iterative; the design-goal-setting process is itself iterative. Knowing complete product requirements up front is a quite rare exception, not the norm. Therefore, goal iteration must be considered an inherent part of the design process.
