Geometric Umbrella Tops in Ribbed Concrete Lobby

Honey-colored light floods the ribbed concrete lobby in Skikda, casting warm tones across a dense cluster of umbrella tops viewed from directly above. The curved canopies form a tight mosaic of deep reds, navy blues, and charcoal grays, their surfaces catching the late afternoon sun while the surrounding floor remains in cool shadow. Strong tonal separation defines each curve against the rough, textured concrete walls that rise in vertical ridges. Lamplight begins to settle into the far corners, adding a faint, steady glow to the recessed areas. Negative space frames the central arrangement, showing the graphic rhythm of the overlapping shapes and the stark contrast between the soft fabric textures and the hard, industrial architecture. at the edge is a sharp shadow line where a canopy edge meets the floor.
