This image does not represent an architectural facade, but rather a decorative ceramic tile with an artistic floral motif. The tile features a cream background with a stylized blue flower (presumably a poppy) with green leaves and a bud. The work is executed in glazed ceramic technique with characteristic Art Nouveau or Art Deco fluid, organic lines.
Although this is not an architectural facade element in the direct sense, similar decorative ceramic panels were often used in late 19th - early 20th century architecture as embellishments for building facades, especially in the Art Nouveau style. Such ceramic inserts could be placed above entrances, windows, or as decorative panels on exterior walls of buildings.
For contemporary facade design, similar ceramic elements can be used as accent details, giving buildings individuality. They pair well with brickwork, stucco, or modern materials, creating an interesting contrast between historical decorative elements and contemporary architectural solutions. Ceramic panels can be used to highlight entrance areas, frame windows, or serve as standalone decorative elements on blank wall sections.
