Patterns. Christopher Alexander.
Most modern buildings come from blueprints, drawn as shown. They don’t allow the design to evolve much during building, it’s a two-dimensional pattern pre-determined on the draughtperson’s table. So the buildings don’t really live. A building is not an object, it’s an interactive, ongoing creation. Patterns of movement and activity and materials determine how a building is built and how it gets shaped over time. Stewart Brand wrote a wonderful book about that.
