architectonic adj.

"person skilled in the art of building, one who plans and designs buildings and supervises their construction," 1560s, from French architecte, from Latin architectus, from Greek arkhitekton "master builder, director of works," from arkhi- "chief" (see archon) + tekton "builder, carpenter" (from PIE root *teks- "to weave," also "to fabricate").

Old English used heahcræftiga "high-crafter" as a loan-translation of Latin architectus. Middle English had architectour "superintendent." Extended sense of "one who plans or contrives" anything is from 1580s.
