Welcome to the Membership Office at patternlanguage.com!

Our site is supported by member contributions so we will never have to run any ads ever.

From its conception in 2000, patternlanguage.com has been a membership-based site, and without our member contributions we would not be able to continue the site, an ever-expanding resource on Christopher Alexander’s work.

Patternlanguage.com is a program of The Center for Environmental Structure, Alexander’s architecture firm founded in 1967, a non-profit 501(c)3 company.

As a member, you will have access to exclusive content, including unreleased archival and planning documents, and access to the original hypertext of A Pattern Language online, which was arguably the first complete hypertext book available. In the future, we intend to have more ways for members to contact each other, which is commonly requested by our online community.

Please join today to support the continued work of patternlanguage.com, Christopher Alexander, and the global pattern language community.

We appreciate very much your support as we welcome you to explore our extensive, ever-changing website. Please contact us with any questions, and, good luck with your building!

All the best,
Sophie Alexander and the patternlanguage.com team
