What decorative motif often appears on the Hoover Building's facade?

Lotus flowers are a decorative motif that often appears on the Hoover Building’s facade.

The Perivale building is celebrated for an Egyptian-influenced form of Art Deco. Its designers, Wallis, Gilbert and Partners, used stylised lotus imagery alongside monumental columns, geometric ornament and vivid coloured tiles. The motif helped give the factory a ceremonial, almost temple-like appearance rather than the plain industrial look associated with many manufacturing buildings.

The facade was conceived as advertising architecture: a bold landmark visible to drivers on Western Avenue. Its white exterior, coloured detailing, recessed windows and elaborate central entrance made the Hoover factory resemble a modern palace. The Egyptian references were part of the wider interwar fascination with ancient Egypt, often called Egyptomania, which influenced Art Deco design after archaeological discoveries and exhibitions made Egyptian motifs fashionable.

The Hoover Building is also known for a prominent geometric sunburst above its entrance, so “sunburst” may arise in descriptions of its decoration. But among the answer choices, lotus flowers are the specific botanical motif associated with its Egyptian-style columns and facade ornament. Ankhs, palm leaves and papyrus are plausible Egyptian associations, not the best answer here.
