The image presented shows not an architectural facade in the classical sense, but a decorative panel or mosaic with a floral ornament. This is an exquisite work in the Art Nouveau style, depicting a stylized tree of life with a symmetrical composition.
The ornament is characterized by fine lines of brown branches that organically intertwine and create a unified structure. Green leaves of various shades (from light green to gray-green) are arranged symmetrically on both sides of the central axis. Yellow floral elements, resembling rosettes, are evenly distributed throughout the composition, adding rhythm and accents.
This work resembles decorative elements that were often used in Art Nouveau architecture of the early 20th century to adorn building interiors and facades. Such plant motifs were popular in the works of architects such as Antoni Gaudí, Victor Horta, and Hector Guimard. The flowing organic lines and stylized nature in this panel reflect the basic principles of Art Nouveau aesthetics — rejection of straight lines in favor of the "whiplash line" and integration of art into everyday life.
