“I never knew who I was talking to. I was always worried about the physics. If the idea looked lousy, I said it looked lousy. If it looked good, I said it looked good. Simple proposition. I've always lived my life that way. It's nice, it's pleasant - if you can do it. I'm lucky in my life that I can do this.”
Richard Feynman

Christopher Alexander on Feeling of Materials

This takes me back to the conversation Annelieke and I had about the roofing material used for the deck. I designed for corrugated sheet metal, Annelieke prefered clay tiles (which is what came to be). When Annelieke explained her position based on vague notions of magnetic fields I wasn’t comfortable with it … because neither of us know much about it … not substantial knowledge that we can relate to with any depth. However it is clear that the metal roof would have been a much less involved roof … I chose it because it was cheap and easy for me to build. The choice to go with clay tiles was much more demanding (the roof structure had to be changed / reinforced) and more involved … and in the end not that much more expensive. I also felt, and still feel that a green roof was the most “living” option … but it felt beyond my capacity when the buld was taking place.

“The feeling of a material does not depend on what it is – it depends on how it is handled.”
