Introduction
Roots in Alexander’s work on urban design and building architecture
- Alexander: Each pattern is a three-part rule, which expresses a relation between a certain context, a problem and a solution... The pattern is, in short, at the same time a thing which happens in the world and the rule which tells us how to create the that thing, and when we must create it. It is both a process and a thing; both a description of a think which is alive, and a description of the process which will generate that thing (Timeless p. 247)
