Volume 2, the core of the method, provides a language of 253 patterns, for describing buildings, and how they should be designed. The patterns range over ones for whole towns: 'mosaic of subcultures', 'four-storey limit', 'local transport areas' -- ones for small clusters of buildings: 'small public squares', 'common land', 'individually owned shops' -- ones for individual buildings: 'site repair', 'entrance transition', 'sheltering roof', 'light on two sides of every room' -- and ones for small parts of the construction: 'alcoves', 'ceiling height variety', 'thick walls'.
1999: We are having a house built to our own design. Remembering the lessons of A Pattern Language, I explicitly used the pattern 'light on two sides of every room', by designing in some extra windows -- I hope it works!
Volume 3 describes how the Timeless philosophy and Pattern Language method was applied to planning for the University of Oregon. It explains the process of piecemeal growth, speading resources evenly and encouraging repair, and contrasts it with the more popular, but potentially disasterous, lump development, which concentrates resources in a few large developments, and correspondingly large mistakes.
