To me, I’ve always interpreted the phrase “form follows function” as meaning that the shape of something should come from its intended purpose and utility, usually as it relates to architecture, interior design, industrial design and the like. According to what I’ve read, the phrase originated from another famous (Chicago-based) architect, Louis Sullivan.
In my practice, I’ve generally always made design decisions based on how I think my clients will interact with an object. What will their reactions be upon first seeing it? What about each time they walk into the room? How will they use an object throughout the years, across different seasons, when at home alone, when entertaining guests? How does the object fit with the rest of the furnishings in the room?
My number one focus when selecting furnishings for a room is “Will my clients be comfortable and want to use the items I’ve selected?” After all, what’s the point of creating a beautiful design if it won’t be regularly used and enjoyed?
