Display custom post term or taxonomy

In this specific case, it seems the multiple taxonomies have a clear hierarchical relationship.

Rather than a unique taxonomy for building 1, building 2, etc., these can all be located in a single “Buildings” taxonomy that is hierarchical like this:

  • Buildings Taxonomy:
    • Building 1
      • Floor 1
      • Floor 2
      • Floor 3
    • Building 2
      • Floor 1
      • etc.

This means that there’s only ever one taxonomy to query with get_terms(). As a bonus, it makes it easy to final all posts on all floors in Building 1 or all floors in Building 2.
