Dugourc helped define the Neoclassical style through his use of the Etruscan and Arabesque modes. His work often features symmetrical arrangements of mythical figures alongside classical motifs. In pieces like Le Triomphe de Bacchus, et de l'Amour, he uses clean lines and balanced compositions. He moved away from the heavy ornamentation of the earlier Rococo period. Instead, he favoured a refined aesthetic based on archaeological discoveries of the time.

Modern collectors value Dugourc for the architectural precision of his designs. These drawings possess a clarity that fits well within contemporary minimalist or traditional interiors. The balanced proportions and muted colour palettes make these prints easy to place in a home gallery. They offer a sense of order and historical continuity without feeling cluttered. This work represents a transition toward the structured elegance that still defines modern luxury.
