It's worth mentioning that "A Pattern Language" is just that, it's a language of about 250 patterns that can be applied to urban design, building layout, and construction. If you want to know more about design patterns and how and why Alexander came up with the patterns described in "A Pattern Language" in the first place (which is helpful if you want to create a pattern language of your own to address the needs of a different field), you might be interested in "A Timeless Way of Building". (I would recommend reading or skimming through "A Pattern Language" first, to get a good idea of what Alexander's idea of a well-formed pattern is. It's also a really interesting book in its own right, especially if you have any interest in architecture.)
