Is it possible that no archive exists for particular architect or firm?
Unfortunately, yes. Architectural records may have been lost for a number of reasons. Institutions began collecting architectural drawings in earnest only in the late 1970s and early 1980s. Before then, individual original renderings were more highly prized than groups of printed working drawings and other project materials, which may have been discarded if there was no successor firm or family to maintain an office archive. Fires, floods, office moves, damp basements, and career changes have also claimed millions of records.
