Anarchitektur is the first release of Einstürzende Neubauten's Musterhaus project, a series of highly experimental CD releases that were only available via an annual subscription through their website or from shows during their 25th Anniversary Tour. This project was separate from their Neubauten.org Supporter Project, which it ran concurrent to.
Unlike later releases in the Musterhaus series, Anarchitektur did not have a specific theme to it. Rather, it was general experimentation described on the back of the album as "an outlet to the creative aspects of the band that are more experimental, challenging, and less likely to fit into song/album format of their regular releases", a concept which would continue on through the series as the foundation for each release.
