It is a book of two hundred and fifty-three patterns, each one a small observation about how buildings and towns work, written as an instruction. The patterns are things like Light On Two Sides Of Every Room, or Six-Foot Balcony, the second of which exists because Alexander went and measured balconies people used versus balconies people did not, and found the boundary sat at about six feet.

That is the whole method: notice which places make people comfortable, work out why, write it down so someone else can do it on purpose.

What keeps me coming back is the tone. It is completely without cynicism. It assumes that the person building the thing wants it to be good, and that the obstacle is not motivation but knowledge. Almost nothing else in design literature makes that assumption.

The software people adopted it in the nineties and got the shallow half, the idea of a pattern catalogue, while leaving the part where you are supposed to care whether anyone is happy in the room.
