“My worrying, for instance, was a scene in which I looked at myself while I had the sensation of being boxed in. I call that worrying, It has happened to me a number of times after that first time.”

Christopher Alexander – Fundamental Property 8: Deep Interlock and Ambiguity

Images selected by me inspired by the ones shown in the book.

“In a surprisingly large number of cases, living structures contain some form of interlock: situations where centers are ‘hooked’ into their surroundings. This has the effect of making it difficult to disentangle the center from its surroundings.

… a similar unification is accomplished through the creation of spatial ambiguity … a common example … is the house with a gallery or arcade round it … the space in the gallery belongs to the outside world and yet simultaneously belongs to the building.”
